There was one listed on the back of a "Surplus" magazine a few years ago that came with all of the accessories and was minty for US$25,000.
Mind you, it was a rare pistol made by a rare manufacturer.
That's the problem with milsurps, you can find some real gems at yard sales and some real clunkers in specialty shops.
It's all luck of the draw, unless your willing to pay the prices asked by knowledgeable dealers and collectors.
The last time I saw one go for $50 was about 20 years ago. They were being dumped by Viet Nam and a few other Asian countries. They were in fair condition at best. The decent ones had been pretty well cherry picked by the collectors and big dealers, before the public was given a chance at them.
