I just happen to have a cnc plasma table in my garage. If some enterprising fellow was to send a true dxf. file my way I could very likely cut some parts for " research and development " of a ppsh semi auto receiver. Have a look at the plasma cam web site to see the table I bought. I'd hot link it but I don't know how( nor do I care to learn). Some where I have the book sub-machine gun designers hand book. It's got drawings of the sten and the ppsh. Good book, but Its burried somewhere in all my crap.
