Thank you guys. It's definitely an amnesty gun, but I had never seen a finish like this on an MP40, and was wondering what was "going on" here. Here's what I got from one dealer/collector: __________ I had a chat with Craig about this gun but did not see pictures until now. It looks very good but the bolt is mismatched being off the receiver number by 120, and the mag well is 611, which is also on the receiver forward of the ejection port and on other parts. So, it is a mismatch. The trigger frame screw just forward of the trigger guard is an incorrect replacement for the two piece screw that is factory. My opinion is that it should bring a premium as a Steyr made, phosphated gun, which are scarce, but it is not A-1 due to the mismatched parts and the screw. Steyr is the only factory to use Bonderizing and phosphate finishes on their guns. ___________ On the other hand, I got ANOTHER email from another friend who I respect, who told me this gun was totally screwed-with. The strange thing is, the guy who owns this gun ... IS the owner from the 1968 amnesty, and swears this is how he got it. I would love to get to the bottom of this, and REALLY appreciate your comments, and information.
