Dang.... So Many....
All Time Best: MP-40 Schmeisser, During last amnesty in 1070's, a friend told me his Barber has ben with Patton at the Bulge, he had a "German Burp Gun" he wanted to sell. I ran the old guy down, met him at his shop, he drug out a greasy paper grocery sack that had an MP-40 and two Magazines. There was light surface rust and the Bakeolite panels were perfect. I asked him what he wanted for it, he said $200. I hit him with it so fast... well, I had him hang onto it until I could process the paperwork... wish I still had it, that thing just refused to NOT fire anything that was thrown at it, split cases, pushbacks, inverted rounds.... ( I raided the coffee cans of range reload rejects) what a great gun..
There was a Ruger Mini 14 not long ago for $200.
A Browning Hi-Power with Artillery sights and Waffen Markings for $135.
A Mod 37 Smith J for $185..
An American 180 in the 70's for $275, that I later transferred for $3000
Just recently,
Two Model 96 Beretta's for $400,
Two Mini 14's in SS for $600,
Last one, a Benelli Nova for $100, never fired, and a FAL in 308 for $200, guy just out of work and I gave him what he asked for it, with option to get it back for the same amount...
