That is a beautiful model 375 David. The 375 was SD&G's top offering at the time the gun was produced as SD&G had yet to introduce the "Regent Diamond" quality guns (model 500).

I agree with Doug that the gun is worth more like $10K, possibly more. My first swag at the value, sight unseen, was to give you a floor - i.e., even a trashed model 375 would be worth at least $6K. The gun needs a little cleanup to bring it back to its former glory but nothing too drastic.

Enjoy your gun! The chukars in Hells Canyon don't know what they are in for.
