About 6 years ago, a local dealer & friend had a Triplett & Scott carbine stamped "KENTUCKY". Remember, they were Civil War carbines made in 1865, just when breech loaders & metallic cartridges became really practical. It's personal, but I did not find the T&S to be ugly. Odd, yes, but not really ugly. It handled well, came to the shoulder pretty naturally, and once you got the hang of flipping the action sideways, I think you could have fired it about as rapidly as a trapdoor. We did not shoot it, .50 Spencer rimfires being somewhat costly. I think the T&S later sold for $650, or maybe less. How much would you pay for something that has little historical value, that you can't shoot without going to extremes, and that is basically a wall hanger?

My nomination for the ugliest commonly encountered gun is the Swiss Vetterli.
