I grew up in Maine, and went to school there (as did friend Weer'd Beard). Warren Evans was a dentist in Thomaston (on the mid coast, near Camden). He designed a more or less typical rifle on the late 1860s, but with one marvelous oddity: the stock contained a magazine that held 30 rounds. It wouked like an Archimedes screw.
Evans incorporated the Evans Machine Rifle Company in 1871, setting up a manufacturing facility in Mechanics Falls, Maine (known today for really not much at all). He hoped to interest the Army because of the massive magazine capacity - possibly illegal in some states today.
Alas for Mr. Evans, it didn't work out. The Army thought the rifle too heavy and clumsy, and subject to jamming from dirt and dust. You also reloaded it the same way you shot it - One round, cycle the lever action, load a new round, cycle, lather, rinse, repeat. He got a nibble from the Russian Army, but it was too little, too late. His company folded in 1880.
But the rifle made an appearance in the film Tombstone. Of course, it's in Red Dead Redemption.
So new meme - firearms trivia. And with some old thing from Maine (no comments that I'm some old thing from Maine, if you please). If folks like it, I'll do another. But a ProTip just between you and me, don't go betting cash money on your firearms trivia against Tam. Just sayin'.
