What makes this prototype significant

This revolving rifle blends revolver mechanics with a long-arm platform. The 44 caliber choice was common in mid-century designs because it balanced stopping power and manageable recoil for black-powder loads. The 26" barrel enhances ballistic stability and sight radius for practical accuracy at typical engagement ranges of the period.

Construction and condition

The rifle’s heavy, overbuilt frame suggests a design intention to withstand repeated fire and the stresses of a revolving cylinder in a long-arm format. The finish in the white indicates metal surfaces have not been blued or case-hardened in later life, preserving its original material state. The brass butt plate both confirms period styling and offers a practical contact point when firing from the shoulder.

Provenance and maker notes

The seller notes multiple gunsmiths named Grimm in period records, though no definitive single-maker has been confirmed for this exact prototype (AL7462). The brand listing as U.S. Military & Commercial Long Arms Mfg’s and model noted as Various highlight the piece’s hybrid and experimental lineage.

At a listed price of $5950.99, this piece sits in a niche market for collectors who prioritize rarity, mechanical curiosity, and documented provenance. View product details and pricing to see full images and purchase pathways via the retailer.
