I'm not suggesting an equivalence, but 'khaki' has numerous shades.

Thanks! That will be very useful.

Available in other formats - see here.

I lived near EAMES as a kid (it was my shrine of wonder), and I can't recall seeing anything on nearby brickwork like that.

If there were a version of the Harris Appendix sorted by running number that would be most interesting.

(it was probably the source for GWRorg, back in Mikkel's time).

No. I started the B-set page (originating from Tim Venton's old site), and gradually added information. Mikkel is not to blame!

I can't remember now whether I cross-checked with Harris. I think that will be the first step.

Oh. I've got to track down some old Mike South and John Lewis files, and that may take some while.

Identifcation of the cars is the clue to the date.

I suspect there might have been 3 spring types on the Churchward 3500g - light, medium and heavy. The heavy type might have been introduced before 1925. This pic of 4700, assuming it was taken when the loco was new, would date the introduction of the heavy spring to 1919, but that doesn't mean it featured on the Mogul tenders from that date of course (there were many lots of 3500g between 1919 and 1925). All the Churchward tenders were upgraded when they visited the works, but it's difficult to tell when the last of the lighter springs could be seen in service, possibly late 1920s.

Here is an extract of a drawing from the late Peter Rich, for a Dean 4000g behind the first series of Counties, showing the light spring. The early 'twin strips' form of brake hanger is also shown. The heavier cast type of hanger, as featured on model RTR tenders, didn't feature until many years later (probably mid-1930s).

Hi, was 5330 still in BR Lined Green in the early 60’s? Thanks Fred

Yes. (ex-works, 1957)

Within a few years, it wasn't possible to tell what the livery was. Seen here at Reading, with a different tender:

Shouldn't the bolections be the same colour as the droplights?

Yes.

I sort of remembered there had been a drawing of this van diagram way back in the model press, and a quick google reveals a good RMweb thread.

At 18'6" long, I'm surprised they were rated only 10T.

Is that a 10' wheelbase?

It's a total disgrace we didn't get the Churchward Line.

It is possible I suppose that the tank on 1361 is the same one, six months later, on 1365.

Here's 1365 (at Swindon, 1 April 1949, after a smokebox and chassis renovation and repaint) also with just 'G W'. I've no idea why. ('G W R' with the W on one side of the middle rivet ring fitted ok, as on 1364.)

Impossible to tell whether your 1361 is green or black.

The weird thing about 3335 is that it seems to have changed frames, bogie, and rods at some stage.

3335 with a rare vacuum-cylindered early Dean 3000g with 'G W R' insignia. Date unknown. Could be wartime black.

Again, this is 1908, but I think the dark colour used for the lower part of the walls continued even after the arrival of dark stone.

The colour of the smoke hoods is unknown. They didn't last like that for long!

The pictures you show are pre-WWI, when chocolate was commonly used for the lower part of shed doors. That colour probably continued to be shown until a repaint, which would likely have been in light and dark stone.

Here's Marlborough in 1929:

Is this correct and if not which should they be?

It was perfectly normal for a loco and its tender to have different buffer styles.

Pannier tanks on the Southern Region

We called them 'Coffee pots'.

1924?
