Hi guys hope everyone is doing well. Today I picked up a Baby Browning I traded for a vintage 1970s ARCO mini bike which I paid 250 about ten years old. The gun is in very good condition I would say about 90%-95 on the bluing. My question I know it's fall between 1954 and 1959 the serial number 1408xx proof mark VP under Lion with the letter R under the vp can anybody give me the year it was made? Thank you.
