I'm working on a Martini Cadet and remembered a useful resource for British fasteners etc.: British Tools & Fasteners in New York. In my case, I may need a tap for either BA6 or BA7 (for the rear sight windage adjustment on my Cadet if you're curious) and they have them. $9.68 ea.
I also noticed that they have a tap for 7/32-40, which is used for aperture sight inserts. Yes, Brownells has these as well, but they're $35.00, whereas BT&F show them (in the "Model Engineers" section) for $7.26.
Good place to know about.

ps: I see they also list tools for the old British Seagull outboard motors, if anyone remembers those. (The manual for which clearly stated, "If all else fails, read the instructions.")
