Colombia purchased M1912 long (infantry) and short rifles from Steyr in Austria, both of which used this bayonet. According to Steyr records, 18,500 M1912 rifles were produced for Colombia during the 1912/13 and 1913/14 fiscal years. However, it is possible that not all were delivered to Colombia before outbreak of the First World War ended Steyr's export shipments.

This example has been reworked in Colombia, as evidenced by the grip screwbolts and F-prefix serial number. When originally-produced by Steyr, the grips were secured by rivets with washers.

10,000 M1912–34 short rifles were made in 1934 for Colombia. Steyr had to partner with the Swiss firm Solothurn in order to get around arms export restrictions imposed by the 1919 Treaty of Saint-Germain-en-Laye that concluded Austria's participation in the First World War.

The distinctive "34– " serial number prefix is unique to these rifles and bayonets. The bayonet also carries the distinctive "R. de C." (Republic of Colombia) marking.

This example was gifted by WA collector Scot Sherbert.

The bayonet has been modified by carefully reaming out the muzzle ring, enabling the bayonet's use on the FN Model 1949 rifle. As shown in this comparison image, this leaves the muzzle ring thin, but serviceable. The bayonet was subsequently blued.

The scabbard is Colombian-refurbished, with a neatly-brazed repair on one side. The throatpiece is unusually thick. This scabbard is from a small quantity of short (250 mm. blade) VZ-24 bayonets that Československá zbrojovka a.s., Brno provided to Colombia for testing.

According to Wayne Johnson's 2019 revised and expanded second edition of his book, The FN-49, Colombia received 1,000 FN Model 1949 rifles and double-edged M1949 bayonets from FN in 1952. The book has a ca. 1959 image of Colombian guard troops parading with Mauser bayonets on their Model 1949 rifles.

The Danish Madsen was the last newly-designed bolt-action infantry rifle. Obsolescent by the time it was brought to market in 1951, the rifle included a muzzle brake and rubber buttplate to manage recoil and a windage-adjustable aperture rear sight. It also included a sling patterned on the U.S. M1907 and this unique double-edged knife bayonet as shown in this marketing brochure.

The only manufacturing contract was with Colombia in 1958 for production of approximately 6,500 rifles (reported serial numbers range from 0013 to 6493). The majority were placed in storage and surplussed without having ever been issued.

The bayonet is a simple design, with the hilt and sheet steel scabbard painted black and the blade left in the white.
