Our Assessment: This Lyman Great Plains Rifle, serial number 296224, was manufactured in 1990 and reflects the late 20th century revival of traditional American muzzleloading rifles. Produced under the Lyman name, the Great Plains Rifle was designed to closely emulate the plains rifles of the Rocky Mountain fur trade era, blending historical styling with modern manufacturing consistency. The Signature Series examples are especially regarded for their fit, finish, and attention to traditional detail.

Chambered for .54 caliber round ball with a 32" barrel, this rifle follows the classic long-barreled plains configuration favored for balance, velocity, and effective performance with patched round ball loads. The .54 caliber was historically popular for its versatility on larger North American game while maintaining manageable recoil. The bore rates a perfect 10 out of 10, and the action functions correctly, reflecting excellent mechanical condition.

Approximately 99% of the original finish remains, presenting a near-new example with minimal visible handling. Overall metal and wood surfaces show strong preservation consistent with careful storage and limited use. As a high-condition Lyman Great Plains Rifle in .54 caliber, this rifle represents a faithful modern interpretation of the classic American frontier long rifle tradition.
