Hard to believe there was a day when nobody wanted one, and they collected dust on dealer shelves. Then George Bush the First decided that the 1964 GCA wasn't being adhered to and demanded ATF follow the sporting putpose clause of the new second amendment. Suddenly these became "pre-bans" and people started noticing, but it took nearly 30 years for fixed supply and increasing demand to cause the price to go up, but who would have dreamed over $2000 for a straight stock 56S?

Edit, my apologies for being human and miss-typing the 1968 GCA as "1964". Not only do I know better but I have no idea how I missed it when I proofed this. I am not altering it to make it correct, but am leaving it so that the tyrade below makes sense.
