Very nice H/P.
Reminds me of the Austrian post WW2 contract pistols that were imported into the USA in the 90's. Those were early to mid 50's production w/numbered magazines. Some with their original FN boxes w/cleaning rod for a few extra dollars.
I bought 2 at the time. IIRC they were just under $300 shipped and about 95%+ condition.
The Austrian issue holsters were a nicely made if not complicated drop type with sam-brown type belt rig attached. Other surplus houses were selling them out for $15 or $20 at the time. I bought one for my FN Chinese contract HP too. Looked neat..big spender,,
W. Germany got some FN production early on. I don't doubt this is one if one of the people over on the HP board recognizes it and the holster. The holster looks alot like the post-War Astra 600 W.German issue holster construction as well. ,,Another finely made pistol in 9mmL.
Most of the Austrian contact H/Ps were hand stamped on the front of the gripstrap with LGK(T),,Landes Gendarme something,,the last letter was the district I think. Not all were stamped, but a good number of them.
The 90's imports were 'import marked' as required,,but the importer at the time (Old Sacramento Armory??) did a micro stamping that was to the naked eye a tiny line that looked like a ding or dent in the metal just a fraction of an inch long. It was that small.
It certainly didn't damage to looks of the pistols at all. Many were marked on the flat of the butt behind the mag well.
Extra magazines were available for a while. Original mfg and issue along w/ser#'s stamped on the floor plates. Not that the importer would take the time and try and match them up to yours or any other pistol.
The condition of many wasn't too good. They must have been the range practice mags or something as the floor plates were extremely battered from dropping onto a hard surface (my guess). The rest of the mag was generally ok other than finish wear.
Very inexpensive anyway at the time.
H/Ps, especially the early production are certainly one of the nicest semi-auto pistols around IMO. I'd still own them if I could pull the slides back. Hated to see them go.
