The marks don't look German, and don't follow German marking rules. Can you show a picture of the whole slide, with a ruler to get dimensions?

Those aren't Nazi eagles...

The ONLY thing that comes to mind is that the eagles look like German-style proof marks...

The ONLY Rapp that I can come up with is Rapp Motorenwerke, which after WW I changed its name to BMW.

The Rapp logo is sort of partially maybe similar...

First, 1005 is the Federal Supply Group (FSG) for ordnance materiel. Federal Stock Number 1005-550-8697 (National Stock Number 1005-00-550-8697) is the slide of a M1911A1 pistol. (Bet you knew that!)

So the indication is that it is a replacement slide made under contract to the U.S. or maybe an allied country. I tried to follow up on RAPP/Rapp and came up with a bunch of names; I checked out some, but they don't link to a particular product the company made, only to a CAGE code, so I gave up on that route.

No I didn't know that.

Very interesting.

Well, this narrows it down a lot, as the 11 digit FSN system was in use only from 1949 - 1975. That eliminates all eastern block countries in addition to now sure not being German (should have an eagle over N proof), nor Austrian (should have a NPv next to the eagle).

I don't know the new German proof laws that well (though they probably have not changed much) but in general proof houses do not prove parts. How would a slide fire a proof load? That is why percussion guns sold as parts kits are not proved.

If Rick35ovi can find a CAGE code on the slide (a five character alphameric like 3M256 or 72AX2 (I made those up), we could trace the maker.

The grooves in the spring tunnel are not seen on US slides. Or Israeli.

James, unlike the US that only recognized the receiver as "the gun", German gun law considers frame, slide and barrel equally "essential gun parts" (each of which can get you napped for illegal possession for example). As such, they all get the eagle stamp as part of the process. The actual overpressure proof mark is the mark of the proof house and date.

Can you get a clearer picture of the "horse's head" logo? It's possible that the lettering isn't "RAPP", but something else; you might be able to get a clearer visual if you laid a piece of paper over the mark, then lightly rub it with a pencil, or even used a white grease pencil to fill in the grooves.
