Help identifying and posibly pricing old handgun

[MrSplitshot]

I was just searching S&w message board and found some serial numbers close to mine that were 1922-1925. I found some pictures of older model 10's that look exactly like it. I believe what I read as cto on the side is actually ctq and the last patent number is Dec 29-14 not Dec 09-14 thanks again Steve

Cool. The S&W Message Board is a good one...

Hey guys thanks for your help. It was pretty interesting. Guess my next mission will be dad's old Acme Arms doublebarrel. Thanks again, Steve
