That is a very nice example. The date the guy gave you of 1935 - 1936 does not make much sense in that the Army Air Corps was very small at that time and there would have been little need for such a fine timepiece. I would go along with the early 1940s as more likely as that was when the war was just getting started and contracts for all kinds of war materiel including timepieces were being competed and handed out as fast as possible.

Did you get a paper from the guy documenting this great timepiece? It is self explanatory as it is, but a letter on company letterhead from the ex-Hamilton President would be a major plus to go with it.

Jim, I don't have any document from the president I got it from, he was actually no longer with Hamilton when I purchased it. I am trying to follow up on this now, but its a longshot!
Your right,it is almost certain that 1940, is about right for its origin.
I could also get some idea, from the Sample 49 in the Columbia museum, mentioned above.
Thanks for your input.

If you still have the guy's contact information it would be worth the effort to write to him to ask him to send you a letter with what he knows about it. Such documentation can really add to the historical value and the monetary value as well if you ever sell it.

Where can I get a parts diagram or list for a model 23? I've been searching the site for quite a while without any luck. I just purchased a Model 23 that's missing a few parts.

I can send you a copy of the book I have (parts catalog for the Model 23) for $10 + 2 shipping...(just trying to cover the expense of making a copy and shipping)

Gary, that would be great. Do you have a PayPal account that I can send the money to? Also, I'm looking for a sweep seconds center wheel and pinion. My Model 23 is missing one.

I have a parts tin with some Model 23 - 19 jewel parts. If you have a picture of the exact part(s) you need - I can look for you.

Good to hear from you!
