I realized many people will know exactly what this is, but my knowledge is only relevant to newer models. I also failed the internet with colt identification lol and Colt's serial number search had 30+ models as the result?
What is it, and how much is it worth?
I will also settle for a good website with all the markings and identification marks on it.
Thanks guys

Colt single action army 1873

I'm NOT any kind of expert on the Colt Single Action Army, but by the serial number on the butt it was made in 1890, which would make it a black powder frame.

Check for serial numbers on the bottom-front of the frame and front end of the trigger guard, they should match or parts have been replaced.

The problem is, the US Army had stopped using the Single Action by 1892 except for pulling older guns out of storage, shortening the barrel to 5 1/2 inches, and sending them to the Philippines were the Colt New Army double action revolvers in .38 Long Colt had failed to be effective against Moro warriors.

Since your gun "apparently" has an 1890 serial number the US military had long since stopped buying these and the "US" stamp on the side of the frame doesn't "fit".
Again, look for other serial numbers.

So many Colt SAA revolvers have been worked over and parts been replaced it's often hard to say exactly what you have.

yep, it's a black powder frame, you can tell by the cylinder pin release



It's beautiful

BLACK POWDER ONLY!

Serial number <195,000, and base pin screw.

(late to the party again)

Need detailed pictures of all markings and full numbers - serial on the frame bottom just below cylinder ( in front of where the screw holding the cylinder pin) the Guns serial number. When the government rebuilt single actions serial numbers of parts would be mixed. There were the so called artillery models. Such guns were issued to the rough riders.

Thanks for the replies guys. I will get these pictures and post them.   EDIT: this picture? https://imgur.com/XxlGdOT
