Came across a Springfield Trapdoor rifle (not a carbine) today. Not knowing what were the important features to note, I took only one photo. I couldn't see a year of manufacture, but likely wasn't looking in the correct spots. I can tell you, it appears complete, had double upper stacking/sling swivels and now that I've had a bit of time with the Google, that it has a ramrod bayonet. Beyond that I can bring no more information to discussion. The photo I took was of the markings stamped into the butt tang - attached here.

So, I am curious about what the regimental markings represent, and pointers on what else to look for when I get another chance to take a look at it, especially those things which would help narrow down a value range. I would put the condition at somewhere between at good - can't speak to the bore. I'll take a light with me next visit.
