Century Manufacturing Inc. Model 100 .45-70 Cal
This is a rare and striking Century Manufacturing Inc. Model 100 single-action revolver, chambered in the powerful .45-70 Government cartridge. Manufactured in [Greenfield or Evansville], Indiana, this big-bore revolver is a bold example of American firearm design from a small-scale maker active during the 1970s and 1980s. Built to handle a cartridge traditionally reserved for rifles, the Model 100 features a massive unfluted cylinder, solid steel barrel, and brass-colored frame. This example is in very good condition, with strong bluing, clean wood grips, a tight action, and a bright bore. Only minor handling marks are present. Century Manufacturing produced these revolvers in limited numbers, and surviving examples are highly collectible. Whether you're drawn to its power, rarity, or unique backstory, this revolver makes a standout addition to any collection.

Great shop, great people, very fair in their deals. I sold several items to them and they will be my first stop any time I need something in the future. Shops like these are a jewel to be protected at all costs.

I called because I didn't understand the processes the government requires that prevented me from buying from them. I was quickly educated. And, she even sent me a link to exactly what I needed to do.
