There will no doubt be a proper way to do this, but I can't find a facility that allows me to store snippets of info... I don't know when Andy will be locking down RMWeb3 and whether I will still be able to gain access to old PMs, so to save embarrassment, - dimensions of a batch of PNAs , as kindly supplied by the Fatadder in May (scratchbuilt bodies, for the use of...) . I haven't actually got round to using them, mind, but perhaps this year.(It's the time of year for reviewing outstanding oprojects, progress or lack of it and tasks for the year ahead. This one's on the to do list)

PNA details:

Height - 14

top rib -2.6

other ribs - 1.6

length (excluding end ribs) 105

width (over top rib) -35.7

inner width 31.2

And I should get a proper blog update on the outstanding steam age vans up in the next day or two. I might even have the couplings on them by then so they can be released to traffic

Addendum - New Year's Day, the year after the end of time...

Just to add some further detail on this one while I'm about it: the Cambrian POA/SSA kits come with a lot of extra bits, including several types of solebar. While the Bachmann PNA covers one type of the wagon, PNAs seem to be a motley bunch, built on a variety of second hand underframes of varying lengths . There is a reasonably extensive section in the recent Burkin/BRM book Modern Wagons in 4mm Scale, which quotes wagons as having lengths of 28' 8" over buffers / 101 mm over headstocks (as Bachmann) , 103.5mm over headstocks , and 106mm over headstocks. The Cambrian solebars are 104mm long , so you get a varient with a very different underframe and length.

Going through the photos turns up several wagons at the 103.5mm length, and CAIB3840 - disc braked , Gloucester suspension units, straight solebars , with 7 ribs spaced very differently to Bachmann and very minimalist underframe equipment - looks the best candidate (p99 bottom). It will certainly be a little different from RTR. One issue may be sourcing suitable transfers for the very weathered Railtrack lettering

I think, as near as I can make out, it's one of these:

It ought to be a reasonably straightforward scratchbuild job for the body.

I had understood Cambrian sold their plastic fold up axle units seperately , but can't find them. I may use conventional W-irons as an emergency fudge to attach the moulded plastic suspention units to

(Given how long its taken to find the Burkin book, I badly need a clearup in the study . And yes I am putting everything here so I can actually find it easily...)
