My real interest would be something older -- I would like to learn to fire a muzzle-loaded Civil War rifle. I'm not sure where you start; can you buy a real 1861 Springfield? A replica? What's the process?
You should start at gunbroker.com. They have a whole category just on civil war weapons (many swords, a bunch of guns). It's like eBay, so look around at what you like and what the prices are. If there is something you want to buy, you buy it and have it sent to a local gunstore to process the paperwork.
