I have a Parker double barrel 10 gauge magnum that I purchased around 1976 from an old timer who was no longer able to get out and hunt ducks or geese in this club I used to belong to. I used it a few times, but that is a lot of fun to haul around in the marshes but it was fun.
I would like to find out the value of my gun for insurance policy.
Any help on where I can proceed would be so greatly appreciated.
Here is the info I have been able to gather so far:

10 gauge magnum
Serial number: 69569
Mfg date: 1891
Frame size: 3
Barrel weight: 6 (then a small 1)
Grade: 2

There is a sling attached to the gun when I purchased it and the owner said it was on there when he got it but no idea when he became the owner.

Kindly,
Jim
