I think this is really a Model 1933. Anyway it has a Weaver T03 stamped steel side mount with a Weaver 3/4 inch scope on it. Side mount is attached with two screws that have large knurled heads on them. Does anyone have any idea what size these screws are and what the pitch is on the threads? Just an example 6-40, 8-40. etc.

Thanks for the help.
