Saw an old movie last night (Springfield Rifles). It was set during the Civil War and had plenty of Colt 1873 SAA’s and the star of the movie, that beat back the Confederate charge, was the Trapdoor Springfield rifle in 45-70. Unfortunately, they did not time-transport AK-47’s instead.
Watched the Star Trek episode “A Private Little War“ where the Klingons supplied one group of primitive people flintlocks. So Kirk has Scotty whip up a supply of Flintlocks for the other tribe.
The Flintlocks were Trapdoor Springfields with fake flintlock hammers affixed to the regular hammers. Actually they were very fake looking and quite laughable to anyone who knows better.
