lifter input needed

[B. Dudley]

I think that there is usually a bit of variation in screw widths from gun to gun.
I have a lifter here that is close to your vintage (S/N 18XXX). For the top tang screw, the Brownells 300-2 bit is the best fit out of the thin set, but that is a hear loose. I find that the 293-231 in my wheeler set is a better fit. It is a bit fatter. It is hard to tell the lower tang screw on this gun since the slot is a bit opened up on the ends. But the slot was wider than any of the thin bits to start with.

I have found that my large wheeler set and the Brownells thin bit set gives me nearly all the bits that I might need.
