Here's the parts stash for the Speedwell roadster plus the new 30's Speedwell racer. The Sturmey front drum is a '49 model.

I added the saddle as the one that came with it was super narrow. I haven't ridden it yet - it has no brakes or gears. It's my size but I can't do drop bars anymore - I did 'scorcherise' the Speedwell roadster on the weekend with some flipped north road bars and that much drop seems OK, so maybe I'll try it on this red bike. I'm also thinking I might use a Sturmey S5 hub in the red bike.
