I have a lot of P.38s, but I don't think I have a polizei proofed one. Never went looking for them and when I found one they were more $$ than I wanted to pay.
Probably should have put one in the collection as I have other polizei proofed pistols, but ---
British proofs to me are no different than the importers marks on guns here in the US. They only show that the gun came into the country after a certain time. Unless the billboard dot matrix type marks, done by a couple of idiot importers, they would not keep me from buying a gun that I needed in my collection!
