Sidearms & Scatterguns Colt single action 22lr from 1875

[Dschapp44]

Came across an old colt single action chambered in 22lr. The three patent dates on it are below.

1871
1872
1875

Tried to do some research and googling but came up with little outside of Wikipedia. Was wondering if there were some colt collectors on here that could maybe provide some insight into the pistol. Thanks and have a great day
