It would be a 2. Likely a worn 2 stamp. 7 feames werw only used on 8g hammer guns.
The forend sure looks original. What makes you thinknit is not??? Especially if it has the drawbolt and 1pc forend loop. And the buttstock is original. Just heavily altered. The safety being filled in, if engraved over, is factory. The gun was ordered without a safety. Common feature for a target gun.
The metal condition is great and it is a vent rib ejector gun. It is WELL worth the $3k even with the stock issues. Considering that is it did not have the issues, it would be a $7- 9k gun.
What is the delemma here?
Agree 100% on all points. The forend is 100% original. From what I can see in your photos, this is a nice gun except for the buttstock. I would break my hand going for my wallet for this gun at $3000.
A butt transplant by one of the better craftsmen here such as Brian would make this a superb Sporting Clays gun, along with a little choke work.
