Hi Rob, CME & Cynric,
many thanks for the comments, much appreciated.
Rob, I made the stand over 25 years ago from a piece of maple that was surplus in our joinery shop following construction of an office block in Wembly, the ballast is probably from Slaters, I just cannot remember but certainly long before I started looking for alternatives of such materials.
Cynric, yes it is 50' and is one of a batch built in the 40s. This particular vehicle is currently in Eastleigh works having been sold buy DB Schenker/EWS to London Underground and being converted for their use.
As an aside but linked topic, EasyBuild (Shawn Kay) is having more than a passing interest in the three similar vehicles built at Swindon, DB999506 to Lot 3095 in 1962 and DB999508 & DB999509 to Lot 3379 in 1963 and all to Diag 1/552. DB999508 was ultimately converted and operated by Serco as part of their Track Inspection Train and is currently to be seen as the single unit Track Inspection Coach - painted plain yellow and wedged between two Class 31s or the like. I have been fortunate in finding somebody who actually works in the coach and he has supplied me with a vast array of detail photos - so come on Shawn with the kit and I'll get the scalpel ready!
DB999508 has carried the following liveries (all acknowledgements to the photographers concerned) hopefully in correct chronological order.
