I know it is .0?15 Dia. Can someone measure it for me? Thanks in advance..  Part 2 This number is impossible to read can someone measure it with calipers or a Mic? Thanks again Top most back edge to front of slide.. The number I think it is .166 or .168 but I could be way off.

0.136 A little hard to measure with a caliper, but there's no way the part that I have (from a GCNM) could be .166 |
This is what the image looks like  |
Maybe 0.134 +/-.002 ???? |

According to Volume 2 of Kuhnhausen's book, ordnance spec for the small hole diameter is 0.0845 + 0.001 and the pin diameter is 0.0845 - 0.0015. For the large hole the diameter is 0.280 + .005 and the mainspring cap dia is 0.279 - .002 (see pages 166 - 167). Hope this helps- |
Can you also look up what it says about Knurling at 16 lines per inch? |
