Welcome, Arnold.

I'd first determine if the gun has been hot blued. If so, I'd walk away. Then, if the barrels have been cut, and/or if the chokes are original, or suitable. Have the bores measured for evidence of back-boring or excessive honing. If all the above checks out okay, if the rib's joints are sound, and the wood is decent, that's probably a decent price.

May God bless America and those who defend her.
