Pic #1 is of the Bunn Illinois Watch Co, Springfield. Pic #2 is of etching that says Adjusted Temp, and Five positions. on the rim it has What I'm going to assume is the Serial No# 3207391. Pic #3 is of the etching which says 17 jewels. Pic #4 is of the inside of the back cover in which it has yet another No# 595227 stamped into it under the words Base Metal which is under another stamped symbol of a keystone with a C surrounding an O in the center of it and it has the word Keystone stamped directly above it. I also found some very very tiny numbers and letters hand scribed in 3 different places, which although I was able to read quite clearly I couldn't make heads or tails out of. I am thinking they are just possibly 3 different inspection marks which were scribed when they were finished at the separate stations of an assembly line.
