Brings back memories. I remember this episode about a 20th century Rome.
Same SMG that was used in the original “Planet of the Apes” movies, but with a “futuristic” wooden stock. The carbines, with a similarly created stock, were .30 M1 Carbines.
Madsens are very cool little SMGs. Easy to maintain.
That was the episode with the infamous Kirk vs. Spock gladiator fight that they parodied in “Cable Guy”, right?
It appears to be slightly more refined than the M-3 grease gun and holds a couple of extra rounds.
At a start trek convention, I saw a blooper real that included the cue-ball helmeted shock troops double timing into the cell block, with a guy in the back row losing his footing and sliding home safe!
