Here are two. I paid $800 couple years ago for the blue one, cheap because it had broken grips at the time. The nickel one, $900, had its original hard rubber grips. Blue DAs are scarce and command more price than nickel ones in same % condition. I have others but these are the only pix I had in photobucket.

I hope this is helpful. Keep checking gunbroker.com auctions. They usually have big S&W DAs listed. There is no difference in prices for .44 Russian or .44-40 in my experience.
