Yes, sorry for the confusion. I should have known that a 1945-built car wouldn't have been the same as the prototype of the Branchline car.
The car I'm thinking of doesn't show up today so it must be in storage. But I did find a different Branchline car, factory numbered 20558, in a repaint scheme (the Western way with large initials) with a shop date of 1961. I believe this is the same series of car.
I need to find that other one and weather it a little more, to represent a 1960-era condition.
