France did not acquire this gun but the US Navy purchased 77 examples, the US Army 19, the latter seeing action in the Indian Wars, in Cuba and in the Philippines. Initially the round used a coiled brass case, but in 1891 a drawn brass case was introduced, all of the known examples being made in this year by the Winchester Repeating Arms Co, as a result of which the cartridge is sometimes referred to as the 37 mm Winchester.

Dated on the case "5-91" and on the projectile "4-91", patent day November, 14-76. Overall length with the common shell loaded was 204 mm. The round is inert but still has a live primer.
