I apologize if this is not in the right sub but I didn't see one for pump 22s.
I am looking to repair a 29B that had a broken Operating Lock Spring Screw. I have drilled it and need to know what size screw it was? Was it a #3-48? That is my best guess from the hole size what I could salvage from the threads and using a thread pitch gauge.
Thanks for any help I can get.
