Well Michael, We wouldn't recommend you disassemble your Parker if you haven't had prior experience with Parkers before... but... in view of the fact that the original DH stock has been replaced with a stock from a GH and even that one has issues, maybe this is a good gun to practice on.
First, before attempting to fire it you should have it thoroughly checked out by an experienced double gun smith. Barrel wall thickness is critical in these old guns because they were extensively used in the day of black powder and corrosive primers and many old doubles became deeply pitted in the bores and a good many of them have had the bores reamed even to the point of dangerously thin barrel walls. If they check out okay then I would say it is probably safe to shoot.
Value? Whatever you paid for it establishes its current value.
