All I know is that it was my Grandfathers and my Dad gave it to me about 10 years back. He has since passed and the watch was serviced but the service person wasn't able to fix the setting feature so it works well and keeps great time, but you have to wind it at just the right time, so eventually I'd like to get that fixed. Since we all lived in St. Louis, I would imagine it came from somewhere local but not for sure. The only other ones I've seen look identical BUT they have the individual minute hash in between the 5 min markings which mine doesn't have. If you have any info on it, know any type of valuation on it or know someone who can repair that time setting feature, please let me know. At this time I probably can't afford $500+ to get it fixed.
