You are looking at a Reising M50 Machine Gun. The M50 was used by the Navy, Marines and Coast Guard. The weapon was very comparable to and even considered by many to be better then the Thompson. But it was not used very long. There were two separate models: one for military and one for police departments. This M50 is In great condition and functions great. Comes with 1 Original Mags that are impossible to find (NOT 4 Mags, as pictured). Additional mags can be purchased for $150 each. The maker of this gun according to ATF paperwork is Harrington and Richardson. This gun is currently incoming to MWT on a form 4, so we will accept 50% payment up front with the other 50% due upon the M50 being received into our inventory. Then the gun will transfer to your chosen FFL/SOT on a form 3 efile (1-2 days for approval). SN 55357
