Anybody have one of these?

[Independence Arms]

American Standard Tool Co.
.22 caliber, 7 shot
This one is Pre 1859, judging by this site http://www.baconfirearms.com/Cartridge4.html

I've had this kicking around in my safe for years, and just now decided to take it apart and see what it's all about. Pretty interesting little piece of crap!
I'd like to hear some input from others with experience on them.

Nice little copy of the S&W # 1. Wonder how it would shoot with something like CB caps seeing as they use only primer? (I would guess modern smokeless .22 short would be a no-no?)
