Well since you asked, here are a few of my favorites:

New Model Number Three, 44 Russian caliber. Shipped August 1882, refinished at the S&W factory March of 1965. Classiest gun I own.

Yes, I do shoot it. No point owing a fine old gun if you ain't going to shoot it. Black Powder only of course.

Coolest old gun I own. S&W 44 Double Action, 44 Russian caliber, shipped October of 1881. Yes, I shoot this one too, Black Powder only.
Here are some other favorites, although not quite so old.

M&P, probably circa 1915.

K38 at top, M&P Target Model below.

M&P circa 1948 at top and Model 10-5 circa 1968 at bottom.

A very early 38/44 Heavy duty. Shipped September of 1930. Incorrect grips.

44 Hand Ejector 2nd Model. Date unknown at this time, currently being lettered.

2" M&P circa 1948

Model 36. For social occasions.

Brazilian 1917s. When just one won't do.

Model 19-3. Bought brand, spanky new in 1975.

Model 17-3. Also bought brand, spanky new in 1975.
I have a few other favorites, but don't have photos of them up at this time. Yes, I shoot all of these guns. I only have one safe queen, an early Model 27.
I don't know where we're going but there's no sense being late.
