Tamara, anyone: what is this rifle?

I took photos of it in February, can't recall the name of the gun.

Oleg,

Long time no e-mail, compadre.

Your rifle is, I think, a Burnside 4th Model Percussion.
I wouldn't have known that except I saw that same model on Sarco's site over the weekend and remembered it. They have one for sale at $1195.

YUP:
Looks like a Bunside to me too. Or is it "Sideburn" LOL
