Can't remember the exact year, mid 60s, I had an awesome tommygun. Finned barrel, cuts compensator, they even copied the flip up ladder rear sight.
box magazine (fixed, it was a toy), the only thing that was "off" was the whole thing was OD green.
It was so cool, as unlike the "toy" toy subguns, where just pulling the trigger made a continuous RAT-TAT-TAT, mine, you pulled back the M1 style cocking knob, and as you pulled the trigger, it moved forward, RAT-A-Tat-Tat...
Then you had to cock it again!
Can no longer remember if it was Mattell, or not, but a lot of the good stuff was...
Also had a Man from U.N.C.L.E P-38 that folded up into a camera!
good times!
