These are an East German, postwar Walther PP. These are considered gunsmith specials, and were hand sorted by an enthusiast of these firearms. In his words:

“These were refinished but not completed because of either a problem with a small part or some other minor nonconformance. With a decent amount of work, you can expect a nice looking shooter. Expect to receive a predominantly disassembled, but majorly complete firearm, refinished but possibly missing a minor part or having a part that is nonconforming in some way. No guarantee as to numbers matching or bore condition, but most are acceptable.”
