Unregistered DEWAT most likely. Ask the guy to take pics of the boltface and the breech area…… If it is an unregistered DEWAT from the retail DEWAT days of the fifties, many MP28s had the boltfaces welded over and ground flush and the breech area filled with arc weld. Cadmus Industries in CA did a lot of MP28s this way in the mid 1950s including one I bought from them at that time. Over the years I've come across quite a few more done this way, mostly registered.
Anyway, someone needs to ask him about the welding too find out what's going on.…..
Right. Just spoke with the gentleman and he says he has found the original 'dewat' paper work. It is an original,welded and de-milled per ATF specs at the time. School'd him on the differences between a dewat...old style,a registered dewat,a 1919 style rebuild of a former FA gun into a legal semi-auto and the many different type of guns made from kits. His name is Mike and he asked several good questions. Hope I was able to help him and he said he would post the ATF paper work with his sale.
MP28 is an IMA dummy gun, with "paperwork" being an affidavit submitted by Mark Dotten, former IMA manager, to ATF describing the destruction to the gun to comply with dummy construction regulations.
I e-mailed the owner and he put pics up on his auction of various aspects of the ATF required damage to the gun. Bolt and firing pin appears to be new repros.
Confusion due to inexperience with terminology by owner, etc…..
