I recall reading (but I don't remember where) that there weren't many of those 707's ever sold in the States. Something on the order of a few hundred. I've always wondered about the accuracy of that "fact", because I owned 2 of them. Committed the cardinal sin of having the barrels whacked off a 30" gun; gave it to my son when he was in his early shooting days. I tried hard, but I couldn't keep the kid on the straight and narrow. He ended up liking OU's better.
