In 1960-61 Stoeger listed a 1960 MC model with the same stock as the 1956.MC models are also observed with MCA series stocks. Pre-WWII Mannlicher-Schoenauers existed in three action lengths, small (1900, 1903), medium (1905, 1908, 1910) , and large (1924, 1925). In the Pre WWII era, catalogues offered an unlimited range of variables of made to order rifles and carbines.
No factory Mannlicher-Schoenauer in that caliber has been formally observed. World War II era production was marked “Made in Germany”, complete with proof marks. The latest observed proof date for a post WWII Mannlicher-Schoenauer is 1971, with rumors of 1972. As a group, the Magnum models probably make up the bulk of the true rarities among Mannlicher-Schenauers.Post WWII actions are of the M1924/25 standard size, or the M1958 magnum. The best place to see this huge range of options is in the 1939 issue of Stoeger’s . In the M1950, the 6.5x54mm returned with an 18.5 inch carbine barrel that remained standard for that caliber throughout the Post War production. The clip guides were removed during the transition from M1950 to the M1952, same changes apply to the swept back bolt handle.The so-called “GK” stock design was standard during the 1950-1952 series. In 1964-65 US market MCAs began to be drilled and tapped for Redfield scope mounts 7.The NO may also have been available in the MC serial number series. Although Mannlicher-Schoenauer production officially ceased in 1968, some examples have been observed with proofmarks indicating 1970 and later as the final year of assembly. For a serious case of confusion, see the Mannlicher-Schoenauer section of the of 1962. The only metric calibers offered to the US market after 1960 are 6.5x54mm, 7x57mm, 6.5x68mm, and 8x68mm.Therein are listed the 1961-MCA, 1960-MC, 1952-GK, Magnum, and Premier, all have differences. However, unofficially, the 6.5x55mm, 6.5x57mm, 7x64mm and 8x57mm were offered as USA special orders throughout Post War era production. During the M1950-M1952 series production run, Stoegers listed 18 variations of the Mannlicher-Schoenauer in their catalogues. The M1950 NO series was listed by Albrecht Kind as being offered in 6.5x54, 6.5x55, 6.5x57, 6.5x68, 7x57, 7x64, 8x57JS, 8x60S, 8x68, 9.3x62, .243, .244, .270, .280, .308, .30-06. The Model MC appears in catalogues as both 1956-MC, and 1960-MC 15.
