clutch and primary chain

[bluejay]

I have a 1953 A-10 Golden Flash plunger, the primary chain is a triplex type and the clutch can only take 4 friction and 4 plain type plates, it has 6 bolts springs and cups , I didnt have any problem putting it together using new plates and chain along time ago. These dont match the 1949 to 53 model A BSA spares book I dont know if I have an orphan A-10 or someone has modified it sometime before I got a hold of it. I am not sure, but I seem to remember reading some where, BSA exported this type to north american market. Does anybody out there know anything about this?    thanks,     Jim.

Jim,
         The triplex primary was used on the Super Flash and also, I believe, some of the US export bikes.
I had an engine sprocket which was on a BA10 bottom end but have given it away.

Learn something every day. I thought the triplex was only on the A50/65's
