Does anyone know of a source for 10-30 screws? These were widely used in the early 20th century (by Victor, General Electric, and Ford for example) but seem to have disappeared completely.

I usually make what oddball screws I need. How many do you need? What head style?

Thanks for the generous offer. I may have to take you up on it. What I need is a setscrew for this early (c.1922) Rockwell hardness tester. There may be no way now of telling what the original screw head was - I'd be happy with an ordinary slotted round head (obviously no Philips in 1922), length approx half inch.

I feel a little guilty leaning on somebody for a thing that probably still exists in quantity... somewhere. Let me do some more searching first.

Very cool!!!

Let me know.

I read that 10-30 was used on Ludlow typewriters. Maybe an old time typewriter repairer can help you out.
