Very brave taking on Cambrian wagons, but you seem to be getting good results from them. The Stenson parts are good, aren't they?
By the way, before you put the transfers on it, isn't the BDA actually a BEA - as a result of the pressed steel (as opposed to solid wood) stanchions? That was always my understanding (and seems to be confirmed by this: LTSV Wagons - Profiles). But perhaps there was just some general sloppiness in re-lettering they came back out of departmental use (as yours has), and they were all coded BDA regardless?
