I just picked up this nice GP 40’s ? military style bumper auto.
It runs quite well, but I want to take the movement out of the case in order to look it over more, and tweak it a bit.
I can get the ring and crystal off the front ( one piece case ), but now my question is should I assume this is a pull off crown, or does it have a two piece stem like a Hamilton CLD, where you align the stem and the movement falls out ?
