I have no facts at the moment, but I heard a friend (who is into K-guns) talk of them once, and didn't have anything good to say about them, "definately not a worthy successor to the Krieghoff 32" as he put it. They were short lived also.
I lived and worked in West Germany in the late '60s thru the mid '70s. While there I purchased two "Europa - Model 62" shotguns personally from Victor Brandl in Munich. One was a Skeet Gun with 28" barrels and the other was a Trap Gun with 30" barrels. I sent the Skeet Gun back to the US and had Purbaugh install a set of his 20ga, 28ga and .410cal skeet tubes which I used for shooting American Skeet at US Military bases throughout West Germany. Prior to moving from West Germany back to the US I sold the M62 with tubes. I still have and shoot my Trap M62. Years ago I had Hal duPoint fit a 32" top single to this gun with serial numbers to match that of the M62 receiver. I have had Krieghoff International do an upgrade on the receiver and perform several CLA's on this gun. With the exception of the engraving on the receiver my Trap M62 is a 100% Krieghoff gun. The O/U barrel is marked: MODEL 32 - 12 GA. BOHLER LAUFSTAHL and on the bottom of the lower chamber there are proof stamps, serial number and " KRIEGHOFF ULM". Some people mistakenly think that since this gun is marked "EUROPA -MODEL 62" it was imported by Hal DuPont's EUROPA CORPORATION as a M32, engraving added to the receiver and sold by them as a EUROPA CORPORATION product. This was not the case.
PS: Somewhere in the shooting world there is "my" M62 with Purbough Tubes that I would like to buy back.
