i've decided i want a Thompson and have a few question . i'm torn between the M1A1 and the "typewriter" style. i'm actually leaning towards the "typewriter" but that has nothing to do with my questions 1. Cybergun has both models (71015 & 71016) listed as Cybergun 2. King Arms has both models (43908 & 43807) listed as King Arms Cybergun is there any significant difference between the guns listed as by Cybergun and the ones listed as King Arms by Cybergun? any idea who the Original Manufacturer of the 71015 & 71016 is?
