Looks to be a 31 cal. Manhattan Firearms Manufacturing Company "Pepperbox"

Here's a little history on the company:

It looks like your pistol was made somewhere between 1856 and 1868 in Norwich, Connecticut.

The few that I found at auction are going for $450 (pretty bad shape compared to yours) to one with a letter connecting the gun to the Civil War for $1800.  I did see a couple in ABOUT the same shape as yours with an asking price of $750.

Looks like you have a really nice antique on your hands
