Scott my own bike is 1940 which has been brought up to the later war spec that Ian described. (It also still has the early field stand lug) These are the correct BSA add on pillion foot rests. Ron
I don't know a part number of the top of my head, and can't remember seeing them in my parts lists. The foot rests themselves are the standard part. It's just the clamps that are extra parts. I'll look later and see if they are stamped at all. I'll also look in my 39 and 40 civy lists. Ron
I can't find mention in either the 1939 or 1940 parts lists, or see a number on the obvious side. Probably just something sold as an optional extra or accessory back then. Matty's picture show them clearly, and I just took this of one of mine fitted. Ron
They seem relatively simple to make from scratch, I'm guessing 7/16 BSC bolts and stud?
What size/thickness would you say the strap is made from?
How deep is the foot on that bracket where it sits on the strap?
I have a mate who could machine the brackets easily, although now would be nice obviously!

OK here's a shot from the side. The material for the straps is 7/8" x 5.5-6mm depending where I place my vernier. The lug that holds the footrest is about 2 5/8" long......5/16" fixings. Ron
