Mike:
As best I can tell the gun was made in the 50's some time. That's a guess though. The wood is nice, checkering is still fairly sharp. It's a boxlock with cocking indicators in the top of the action. Weighs 6 pounds.
The barrels are marked F. Dumoulin. I do not see a model number. No engraving, which to me was a drawing point. The stock has swivels and a cheek piece along with a aftermarket recoil pad.
I am guessing that the wood is original. The barrels have been reblued. The case colors are about gone from the action. Inside of the barrels is very good. Started as 65mm chambers.
Seems to me that it was a much better than average gun when it was made.........as if I would know that!
I have about $900 invested in it.
