Leman's trade rifles had a relatively short stock and they were built with both percussion and flint locks - although flint Lemans seem more common. Some of the rifles had a small patchbox and these had a distinctive fleur-de-lis pointing up from the box itself. The rifles had a single trigger and steel fittings - their use by the Indians required them to be rugged and dependable.

Many of Leman's rifles found their way to the Indians since he gained several contracts to provide hunting rifles for Indians. These were produced in relatively large numbers on something like an assembly line. That productivity may be why part of Leman guns occasionally turn up in odd places. A trapper or gunsmith sometimes might take an available Leman part to replace something on another gun that was broken. Leman also provided some parts to other builders.

The modern builder might find this an excellent field or "meat" gun, particularly if careful attention is paid to fitting the stock to the individual's size and weight. We can provide a very good piece of wood and we recommend this be coupled with one of our fine barrels and a good lock - percussion or flint. A double-set trigger could be used and such a modification was probably made by some of the traders and trappers who owned one of Leman's rifles.
