That kind of find is worth building a whole bike around….😎
Oh BTW: the 49 AW on my Humber was also missing the oiler cap: I had understood the filler to be screwed in but mine was somehow peened in place. So I had to improvise and used a tiny rubber stopper for a cap. Took a few tries to get the length right but that stopper has stayed in place for years.
