The import mark was applied using a Hermes engraver, which allowed for precise placement of the marking on the bottom of the barrel adjacent the rear of the front sight. The depth of the import mark varied, making some of the markings difficult to see. Some of these have been later found with the importer marking removed.

The condition of the carbines when they were received by INTRAC has been described as generally very good to excellent condition, with the exception being some of the stocks had been damaged. Very few had rust or pitting. Some of the carbines were in protective long term storage grease. The majority of carbines not in grease were well cared for and sighted in accurately. INTRAC was advised by the Austrians that the carbines had been qualified with yearly, visually inspected, cleaned, and if stored, placed back in storage.

The majority of the M1 carbines had no markings other than the original American manufacturer markings. The largest quantity that had markings, had them on the bottom of the trigger housing (Gendarmerie markings). This indicates the carbines INTRAC purchased also came from the Bundespolizei and/or Bundesheer, who did not mark the carbines they used. This means there are M1 carbines that were imported from Austria that the only clue they were used in Austria would be the presence of an INTRAC import mark.

Many of the carbines had markings from a Bavaria law enforcement agency, but the majority had no such markings. INTRAC was told by the Austrians that their country had purchased several thousand M1 carbines previously used by Bavaria from an American company in 1956 due to the Hungarian Crises. This means there are M1 carbines with Bavaria markings and no Austria markings that the only clue they were used in Austria would be the presence of an INTRAC import mark. Some of the carbines imported by INTRAC have both an Austrian and German agency marking. The Austrians did not disturb German markings that were present (with a few exceptions). INTRAC imported no other M1 carbines, only those they obtained from the Austria. The Austrian company sold INTRAC only carbines that had been obtained from Austria.

The carbines were sold by INTRAC in the condition and configuration in which INTRAC received them. INTRAC did not repair, replace, or switch any parts. Many carbines were received with a leather sling attached (see Austria Accessories), a paper tag with an officers name and location the carbine was used by the Austrian Gendarmerie (see The Carbines, Austria), a rubber rear sight protector (see Austria Accessories), a colorful sticker affixed to the stock in a manner consistent with a rack marking denoting the Austrian unit to which it was assigned (seeking examples), and/or a wood dowel in place of a oiler. If a carbine had one or more of these items when INTRAC received it, when INTRAC sold the carbine the item(s) went with it, undisturbed.

Amongst the parts INTRAC received from Austria were thousands of original GI 15 round magazines and many GI 30 round magazines. BATF advised INTRAC these were in violation of laws limiting magazine capacity. INTRAC rented a concrete/asphalt roller, placed the magazines in their parking lot, and flattened all of them. The metal was sold as scrap. Shortly thereafter BATF stated they had made a mistake, the magazines were legal for INTRAC to import and sell.

INTRAC had arranged for the remaining 7,000-8,000 M1 carbines to be sent in a second shipment in the latter part of 1995. Between the first shipment and this second shipment, Secretary of State Madeline Albright initiated administrative action that prevented INTRAC from importing the rest of the M1 carbines. They were returned to the Austrian company and sold outside America.

Included in the second shipment were M1 carbines used by the Austrian agency known as Zoll (their version of customs and immigration). In the late 1990's and as late as 2007 the carbines used by Zoll were being sold by Euroarms in Italy (see The Carbines, Austria).

You stole that from him.

Yes he did.

An even trade would have been fair with you coming out for the better by a slight bit.  But when he threw you the extra cash, thats when it became robbery.  

Btw, carbine mags are 15 and 30 round capacity.

Your gun most likely came from Austria, slight possibly it's from Bavarian police. Any marks on the trigger housing?

Here's some really interesting stuff I found, scroll down about 2/3 of the page:

You did ok but I believe the collectors really hate import marks so that would cut down the collectors value a bit.

The m1 carbines are great shooters, great fun gun and nearly perfect for the smaller folks (women and kids ) to get started on due to modest size and recoil . Don't get me wrong , they are just fine for regular sized folks also.

The real measure of how your deal went is the condition of the barrel and other parts. Usually the carbines fared well in this respect because carbine ammo was non-corossive from the start.
