I have had this for a long time and it hasn't come out of the closet in many years. I have shot a few grouse with it and it is SUPER light, around 5 pounds I would guess. American Gun Company 410 side by side with hammers. Locks up very tight, no cracks in the wood though I would say it has been refinished sometime in the last 100 years. The hammers both lock up tight and there are NO issues with it at all. I have shot 2 1/2 inch shells through it and would GUESS it is choked F/F but that is just a guess. Price is $800 plus shipping. I very seriously doubt you will ever be able to find one this tight and clean again. The gun will ship in a new hard case and first public "I will take it" trumps PM's. Payment by check or MO is fine.
What are the stock measurements: Length of pull, drop at comb, drop at heel, cast?
Do you have barrel wall thickness measurements?
The barrels are 26 inches. When I lay the gun upside down on a flat surface the butt plate is 1 3/4 inches off the bench. LOP is 13 1/2 inches to the front trigger. I don't own a micrometer to measure the barrels. Hopefully that helps you at least a little. It is a classy old shotgun that is tight as a drum.
No dents in the barrels. I posted the specs somewhere on here as someone else asked. I would guess the wood has been refinished a some point in the last 100 years but I don't believe the metal has been touched.
