Thanks, Hawg!
Here's one I pulled off the 'net as well...an original with case and accessories. It appears to have ivory grips, and is one of the very few examples I've seen with attached loading lever.
Here is a link to the Wikipedia article detailing the Paterson:
https://en.wikipedia.org/wiki/Colt_PatersonWhile it is pronounced "Patterson", it is properly spelled "Paterson", so named for the place it was manufactured; Paterson, New Jersey.
It began production as a .28 caliber, then was altered to .36 cal.
Roughly 2,800 were produced between 1836-1842. It's most noticeable feature was the fold-away trigger and lack of a trigger guard.
