Significant Final Production Harrington & Richardson Model 50 Reising Submachine Gun, Class III/NFA C&R Fully Transferable Machine Gun

A standout collector opportunity, this Reising Model 50 combines important U.S. military and law-enforcement history with exceptional serial-number significance: according to noted author Frank Innamico, serial number “S5607” was the final Model 50 produced in the 1957 run of 907 submachine guns, an “end of an era” piece in American automatic weapon production.

• Desirable Reising Model 50 submachine gun:
  • Closed-bolt, blowback-operated design
  • Introduced in the 1940s
  • Known for better-than-expected accuracy, controllability, and handling compared with many wartime submachine guns
• Historically significant U.S. service background:
  • Saw action with the U.S. Marines in the Pacific during World War II
  • Used as a substitute for the M1 Thompson
  • Found strong practical success as:
    • Defensive weapons for war-essential industries
    • Patrol carbines for American police forces
  • Continued to find a market in domestic law enforcement and foreign export after its military use
• Important place in submachine gun history:
  • Often overshadowed by the more famous Thompson
  • Valued by collectors today as an underrated and more refined design
  • Offered a more elegant alternative to the stripped-down “tube guns” that helped replace the Thompson as a primary World War II military submachine gun
• Exceptional production and provenance significance:
  • Model 50 production continued as late as 1957
  • Serial number: “S5607”
  • Frank Innamico’s research indicates this serial number was the final Model 50 made during the 1957 production run of 907 submachine guns

  • Historically significant as both a wartime substitute for the Thompson and a long-serving domestic law-enforcement arm
  • The reported final 1957-run production status makes this Model 50 especially desirable as a landmark piece for an advanced automatic weapons collection
