Have you been on the LCSCA site?
Lots of information under 'Shotguns' and the 'FAQs'
https://www.lcsmith.org/
The Hunter Arms shipping records at that date should include to where the gun was originally shipped, and possibly the original purchaser. If you are interested that information would be part of a Research Letter

I assume the gun is a 12g? It would then have 2 3/4" chambers.
I would suggest that a double gun specialist check the gun, including examining the head of the stock for cracks.
