Yesterday I went on a 50 km trip on my 1928 model A. Somewhere on the way it lost the intake trumpet, so now I'm looking for a spare. The carburator is a Brown and Barlow, with which the bike was delivered from new.
I found an Amal one in one of my boxes. That could be pressed into service, but I don't like to do that. The Amal one have 24 TPI and the Brown and Barlow is 26 TPI. The outside diameter of the thread is 36,3 mm (perhaps a little worn).
With a little bit of luck, some one out there might have the correct one?
