Mitch, The stock looks period. I suspect it was a Military stock surplussed after the war, never military accepted. Sold into the USA during the 20's-30's. Quite probably with the pistol. Regardless..they HAVE to be seperated now.
I would want to buy the stock for $350 and if it were mine I would be asking $450-500.
The pistol has not changed..It is what it is.

The main challenge is that I am not aware that Pacific Arms marked their work in any way. The only Pacific Arms markings I have been able to observe was on a Pacific Arms Carbine I bought once many years ago. Under the foregrip were some Pacific Arms markings..code I think but certainly translateable to Pacific Arms.

You can also submit the combination of pistol and stock to the ATF and ask for a ruling to have it placed on the "Curios and Relics" list Man..I sure wouldn't jump into that hornets nest given the current attitude of this administration. Better to sell them seperate if selling is your intent. Don't touch the TarBaby IMO.
