Yes please from me too - it would make a nice 7mm industrial kit.

Here's another nice example of crab weathering - albeit in painting form: http://www.railart.co.uk/print-shop/product_info.php?cPath=24&products_id=223

Re. Post 983 - I think I need to get out more.......

Type of fastener depends on frame. If timber then spring head nail, but if purlins (the horizontal side rails to which sheets attach) were of steel - typically angle iron - then hook bolts were used. Hook bolts have been in use for a long time - probably from 1920s? Hook bolt diameter would be 1/4" for very small structures - anything like an engine shed would certainly use 5/16" dia. with square nuts. Hook bolts before the age of plastic washers (maybe 1970s?) would use a shaped galvanised washer approx 1 1/2" square, some were curved so the washer edge sat perpendicular to the corrugations, some were curved to sit at 45 degrees. I can't tell whether the loco shed at Cwym Bach is deemed to have timber or angle iron purlins, but typically a colliery shed of the 40s onwards would I think be all steel construction. Sheet width varied enormously, but the bog standard was an 8/3 sheet, being 8 complete corrugations at 3" pitch. The wider 10/3 sheet was popular for large buildings allowing much faster cladding, and was very common from before WW2.. The actual coverage of the sheets (the distance between sheet edges that you see from the outside) depends upon whether the sheets are overlapped by one or two corrugations. 10/3 sheets with a double overlap give 24" actual coverage, according to my copy of the construction drawings for a WW2 T2 aircraft hangar. The overlap depends on need for economy or durability of structure. Fasteners would be placed at the overlap of sheets and spaced in between to suit budget and durability of construction. Typically sheets with a 24" coverage would have one fastener at each overlap (I.e. one fastener holds the end of both sheets) with one or two spaced along the purlin in between the overlap joints. Many variations existed, so if possible best to go by photographic evidence of actual buildings.

Just realised the photo of P1010 provides a reference for a nice bunker conversion for the Minerva machine!!

A great pair of pictures David - I have been looking for images of the Ebbw Vale engines. The name PONTYPOOL was previously carried by another of my favourites - a Sharp Stewart 'Long Boiler' 0-6-0ST running on the West Somerset Mineral Railway, the locomotives of which were supplied by EV (opportunity for gratuitous image below). The photo of P1010 is a really good one for the wheel designers - it is difficult to compare the proportions of differing diameter wheels as PGH alludes to above. Certainly the larger than usual wheels of the E Class appear quite different to the more numerous smaller Peckett examples. Tony

Well spotted PGH! Must admit that had passed me well and truly by. I hope it is not too late to amend the wheel design - I'd much prefer to wait a bit longer for the correct profile (now I know..… ).

"I'm sorry dear, notwithstanding your keen interest in north eastern collieries, I really cannot agree to naming our newborn child MORRISON BUSTY No. 2 ".

Looks like you went to the trouble of turning the shed superstructure 180 degrees on the brick base too!

Were they like this? Published by MAP - but I can only find reference to this one, No 11 by Peter Matthews (which I have):

Alan - can you point me in the right direction to learn about your 3-D scanning techniques please? I'm looking at scanning various items sized from truck wheels to dump trucks and keep getting told it is way too expensive…... Tony

P2047 of 1943, a Class R4. Supplied to No.2 Metal & Produce Recovery Depot, Eaglescliffe Co.Durham. Some interesting info here: http://www.thenorthernecho.co.uk/history/yourmemories/10189914.print/ 2046 went to No 1 M&PRC Cowley Oxfordshire. Sold 1950/51 to Stewarts & Lloyds (Pty) Ltd and named CORBY for use at their Australian tube plant.

Finally! http://www.royal-arsenal-history.com/royal-arsenal-railway.html A good photo of the stockyard gantry crane, and a map of the rail system - but still no E Class images!

Does anyone have access to the IRS handbook covering Royal Arsenal, Woolwich? There seems to be very little information readily available. A little more from the Chasewater site: https://chasewaterstuff.wordpress.com/tag/royal-arsenal-railway/ - which describes features seen on the photograph here (and which I suspect is the actual photo): :http://www.gres.org.uk/page51.html Whilst the background of the photo showing a stockyard crane gantry could be Woolwich, could it equally be a 1950s Wallsend? Note big rear windows but no bunker. I'm just curious as to why these random modifications should have been carried out at Woolwich. There were more locomotives than just the Peckett E Class at Woolwich (a total of 50 is mentioned in GRES). I would expect more consistent modification across the fleet in such an establishment. Some interesting information about locomotive and wagon construction activities at Woolwich post-WW1 on the GRES webpage too.

That Bunker and other stuff: Below is a picture said to be of a former RA Peckett 1491 / 1917- albeit not an E CLASS - from the very interesting Chasewater blog pages (the only problem with this site is that once you find your way in you can get lost for hours amongst the pages of fascinating stuff!) - I hope they don't mind me reproducing the image below the link. The evidence is leaning towards the use by RA of standard build locomotives at this time, which would suggest the modified cab rear spectacle plate and extended bunker on LION were added later by Wallsend Slipway & Engineering? https://chasewaterstuff.wordpress.com/ncb-west-midlands-division-area-2-locomotives/brereton-collieries-ltd/ There was a note in the Peckett Works Photos book that the Royal Arsenal E Class P1464 NEW ZEALAND was supplied fitted with a spark arrestor chimney. However the only picture I have seen so far of Es formerly used by RA has a standard chimney, but of course this could have been fitted later. It would be useful to find photographic evidence of the use of spark arrestor chimneys on the RA Es. A works photo of a Ministry of Munitions Class R2 Peckett of 1916 suplied to Chilwell shell factory shows a classic conical spark arrestor chimney.

There is some more info on P1351 LION here, including a very useful picture for your purposes David, taken at her second home - The Wallsend Slipway & Engineering Co, Northumberland: https://chasewaterstuff.wordpress.com/tag/plumstead-erith-marshes/ Note dumb buffers, oil firing tank on cab roof and a standard chimney. I'd guess the dumb buffers and oil firing were added by Wallsend (maybe the enlarged cab rear windows too?), but what about the chimney - was she ever fitted with a conical spark arrestor chimney of the munitions factory type for her first role at The Royal Arsenal? When was the rear bunker added?

The most comprehensive review of the Millwall Extension Rly Manning Wardle 2-4-0s I have found is in London's Dock Railways Pt 1 by Dave Marden. A great selection of photos. A very similar Sharp Stewart 2-4-0 HARO-HARO, ex Jersey Railway and Manchester Ship Canal construction, ended up on the Woolpit Brick & Tile's Railway in Suffolk: http://www.elmswell-history.org.uk/arch/railway/haro.html

P1539 / 1919 FURNACE - right under our noses, thanks to Arthur! http://www.rmweb.co.uk/community/index.php?/topic/41515-bsc-landore/

P1565 / 1920 SIR JOHN WYNDHAM BENYON: http://www.tredegar.co.uk/gallery/gallery.asp?action=viewimage&categoryid=100&text=&imageid=7174&box=&shownew= http://www.tredegar.co.uk/gallery/gallery.asp?action=viewimage&categoryid=100&text=&imageid=7193&box=&shownew= http://www.tredegar.co.uk/gallery/gallery.asp?action=viewimage&categoryid=100&text=&imageid=7192&box=&shownew= http://www.tredegar.co.uk/gallery/gallery.asp?action=viewimage&categoryid=100&text=&imageid=7194&box=&shownew= These were found by googling images for 'Peckett 1565'. Pick a number and try it!

If you google the names of the E Class customers a few surprises might turn up. For example, 'Charlaw Colliery' (P1180 was sold to Charlaw & Sacriston Collieries Ltd in 1912) turned up this gem of a picture: http://www.irsociety.co.uk/Archives/53/Transit.htm Here is the image:

Another Ebbw Vale locomotive -1009:

You're going to have to buy 2 x Minerva Pecketts in order to accurately recreate the hybrid locomotive made by Ebbw Vale from the parts of two E Class locomotives - 1465 and 1524: https://www.flickr.com/photos/12a_kingmoor_klickr/5780114381/ Note the extended bunker.

OK - Official Works Photographs: Turns out that the Martyn Bane BEAUFORT is a photo of the first Class M5 built - 1055 / 1905 for the Beaufort Works Ltd of Morriston, Glamorgan. This and a lot more information can be found in a recent book from IRS - Peckett & Sons Ltd An Album of Official Works Photograghs by Andrew Smith. This book will shatter any confidence you might have had in the use of official works photos alone as evidence! It also contains an official photo of the first E Class, 1000 / 1903 (but depicted in the official photo as 1001) for Ebbw Vale, one of 1054 / 1907, and one of 1465 / 1917 (but depicted in the photo as 1464 - 1465 being another Ebbw Vale loco, whereas 1464 was fitted with a spark arrestor for the Royal Arsenal). And a photo of the first E1 (the redesigned E) 2108 / 1950, which represent a possible conversion opportunity for the Minerva E? First glance differences being a modern cab front window profile and straight rear frame The evidence from the photos listed above and others in the thread so far, suggests (to me at least) that all E Class locos were identical upon leaving the factory (other than the move away from Salter safety valves - the last Salter valves being seen on a works photo of 1910, and the spark arrestors). If that is so, then any variations will be of the 'user' variety - which could be pretty much anything….! I would highly recommend the book.

Dave - just looking quickly at the age-sorted pictures on Martyn Bane's site, smokebox handrails might have gone all straight circa 1912? I would the tank lifting eyes were a GWR / BR addition as I do not recall seeing another (industrial user) Peckett so fitted.
