It's marked twice....I'm still going with Colt !!!
Look at the face on the discharge end of the cylinder. If it's a Ruger, you will see three numbers hand engraved on it's face. That will indicate the last three number of the serial number.
Good question and it's a "Peacemaker"Which Colt ya got? Frontier Scout..Peacemaker..New Frontier?
Just curious. What was your confirmation? .....Pahoo..It's a Colt....Looks like they all are marked 22 LR....May all interchange?
Your Ruger might be an older one and do not know when they started etching them or "really" why? All the ones I run into, are etched but will have to look at some more, at the next GS. I know a Ruger "expert" that is really informed on these. ....Pahoo, mine is not so marked.
Attatchment in #14 was a Peacemaker..but I found 22 LR on Peacemaker..Scout..and New Frontier....Funny thing..It was'nt consistant....Marked em sometimes and sometimes not?Just curious. What was your confirmation? .....
