Based on the patent dates, caliber, size, and round butt, you have a Colt Lightning. It is a gate loading, rod extracting double action with a superficial resemblance to a SAA. They are notoriously fragile mechanically, so yours might very well be out of order to where it would not function double action.
I 'm not going to guess on the value, but in the condition described, it won't be great.
Oh, yeah, made from 1877 til 1912.
