I have a few BP pistols and rifles. I recently picked up a Ruger Old Army. She is stainless steel but according to many forums I have read, it should not exist. You see,, it was made in 1973. And supposedly those were only in blued steel. There were 1200 with brass on the trigger guard and frame. But here I have one in stainless with brass trigger guard and frame. Any thoughts on the subject are welcome. Yes, I have contacted Ruger and I am awaiting their reply. Thanks in advance.
