In the Lyman Muzzleloader's Handbook, 1976, most factory guns available were featured in the back section. The Minuteman sold for $199. The TC Hawken went for $205 and the Renegade for $165 that year. These were production guns.
By comparison, the Green River Rifle Works halfstock Hawken went for $500. That was a high quality semi-custom piece using best quality components. Entirely different quality and it was historically accurate. That was the most expensive "factory" gun of it's day.
The Minuteman was one of the few choices of guns meant to represents the longrifle. Many Numrich guns were reliable and shot well. In retrospect, it does not represent any known longrifle style, the patchbox was designed with easy routing inletting in mind, and etc. But for the emerging black powder "boom" at that time it was a way to get a long rifle, full-stocked, that felt as though it was representing an earlier period than the "hawken" style.
