Help Identify

[freekick100]

I'm trying to find out more about a pistol. :banghead:
It is a 7 shot, 22 cal, single-action.

The only markings I can find on it are:
"Parole" stamped on the barrel
Pat'd Apr 23 1878
and I think a Serial Number 1293 engraved on the cylinder and the butt.

Any info or ideas on where to continue my search would be helpful
