Cheers both!
You see, that photo of 4567 is my problem. I’ve elected to fit the cab shutters to this model. That pushes its actual dating to quite late in the 1930s, but still pre-war. It ought to be right to assume when the shutters were fitted during a works visit the route discs would have been painted at the same time on the shutters.
I’ll put the evidence to the client. I think he’s probably going to admit to not being all that fussed, but I'd rather it was his decision.
Transfers (and paintwork in general) always give me the jitters. Excellent timing, when I need a steady hand. No matter how much measuring and markings out, something is usually on the squiff. Indeed, the first transfer above went on crooked, despite all the measuring. It had to come off, and a second attempt was made. That, too, was a bit off, but I have managed to correct it. Extra effort has been made with the other side, but it’ll still be crooked, you can guarantee it!
