Thanks for the info. The s/n under the top strap is 22. Do you know what the letters in the circle on the handle stand for?Your revolver was manufactured in 1910. US Revolvers were manufactured by Iver Johnson using surplus 2nd Model Safety Automatic frames and sold thru the mail. They did not have the safety features that were on the Iver Johnson, such as a transfer bar and the hammer the hammer action. They are considered black powder frame guns and not safe for modern smokeless ammunition.
That low serial number may become desirable for some collectors. The barrel doesn't appear to match the frame. Remove the cylinder and look for the serial number under the top strap.
Missed that, but I was viewing on my phone. Those are not the original grips, they are from a different manufacturer for a different gun. I have no idea what gun they are for.Thanks for the info. The s/n under the top strap is 22. Do you know what the letters in the circle on the handle stand for?
