Blue Jacket Number 2 was a RIMFIRE and, being old enough, is a legal Antique.
I do not know when they entered production (I am told 1879 but have no proof) but they are certainly old enough to have been used back then.
The LATEST reference I can find to that model is 1898..... in a book printed in 1897.
They do not seem to command a heck of a lot of money (around $350 in average condition) but they are one of the nicer of the 19th-Century "house" pistols.
A GREAT little inheritance!
