Might be a military version given the four screws and cutout for a shoulder stock and the "O" stamps?

 

Condemed military sold on the commercial marked I think. If memory serves me correctly that is what the o means. It's on each numbered part.

Thanks for checking it out. I was hoping military and it saw some action in the war!

 

Well it still could have. Maybe it went South. However no way to document that I guess.

Decent looking early piece. Thanks for showing.

 

Maybe I should get the Colt factory letter. Not sure I want to spend the money though.

 

Interesting previous thread:

need help colt 1860 army with odd sub letter on sn# | Colt Forum

 

Just read through the thread. Some great info there. I wonder if my serial number falls in there somewhere. Thanks for sharing it.

 

Solid early piece, shipped late that year (around Nov). So it's a martial contract piece, not civilian (check for faint US on the frame).

 

Might be wrong, but I thought that the original 1860 Army revolvers issued during the Civil War to the Union that were martially marked and also the civilian pieces did not have a U.S. marking anywhere on them. The arsenal reworked revolvers after the war had the U.S. mark on them.

 

True, no military 1860 Armys were stamped ‘US’ on the frame from the factory. The arsenal re-works with mixed numbers usually were stamped somewhere. For some reason Larry Wilson thought it would be cool to stamp the 2nd generation frames with ‘US’.

 

Checked it out really well and I don’t see any U.S. markings anywhere except the top of the barrel which is normal.
