I believe this is a colt "new line" .22, however I can not find one with these patterns on it and it does not have a serial number anywhere on it. I believe it may be a copy or just made by another company but can't seem to find anything to lead me one way or the other
Pretty sure it's not a Colt. Smooth cylinder, crude engraving, hammer doesn't look right. Suspect Belgian or maybe Spanish.
There should be proofmarks on it. Look at the face of the cylinder, under the barrel and under the grips. Guessing you will find
a little oval with the letters ELG and a star, maybe a crown on top of the oval.
