BR Western region wagon liveries

Would anbody know how BR re liveried ex GWR wagons? Im trying to work out what lettering and numbering would be on a GWR type conflat with a B type furniture container. Would it be pretty much the same as BR's own Conflat wagons? Thanks in advance, Peter

 

Wagons from pre-nat companies carried the letter of their original company. i.e. for ex GWR wagons the letter was W, followed by the number. LNER = E, LMS = M and Southern = S.
Wagons built by BR were B, and departmental wagons were DB. Pretty sure there was a letter for private owner wagons, but not too sure.

 

It was P = Private Owner

 

#-o The obvious choice then!!!!!!!!
