The Model 50 is an updated version of the earlier M1946 produced right after WWII. Both used many of the wartime expedient stamped steel manufacturing processed parts developed during WWII. The really interesting aspect of this model is that it is manufactured from two separate stamped steel receiver halves that are hinged at the rear of the receiver and are held together on the front end by the barrel nut. Although it seems very unconventional, it proved to be an extremely reliable and accurate submachine gun based on demonstrated military testing performed in Canada in November 1950 that was witnessed by the Canadian, British, U.S. Army and Danish representatives. In that test, a single M50 SMG successfully test fired over 20K rounds of ammunition in a little over 2 1/2 hours with no failures. As noted, it uses many stamped steel parts except for the barrel and bolt, both of which are machined. It has a right side, folding wire type stock, a grip safety behind the magazine well, and side mounted sling swivels. It has a simple non-adjustable peep rear sight on the rear of the receiver and a blade front sight. The left side of the receiver is stamped with serial number "51-01916" over the sear safety, and the right side has the model and import markings with "MADSEN" on the right center. With three extra magazines.

Very fine. 75% original black enamel finish remains with areas of edge wear, scratches, spotting, and heavy handling marks overall. The grip and stock have a mixed brown/gray patina with visible oxidation. Mechanically excellent.
