Welcome to the site and please feel free to post often. Your pictures are very good!
The engraving is quite unique. The excessive background is stippled rather then punch dot. I don't think the engraving is as near as old as the gun. A nickel gun would not have been engraved when new. The 2 piece ivory grips may also be a more recent addition. The nickel would have to have been chemically stripped in order to get it off. The Indian head also seems to late of a style for a gun of this vintage. Most non factory engraved guns at this time were simple scroll work. The amount of coverage is also more then normally seen at this time. The patina as pictured has a very nice aged look. It looks light brown in the pictures. The metal that is not engraved shows some roughness and is not freshly polished. The barrel address shows no buffing and may be hand engraved vs roll stamped which would also indicate later work. A picture of the serial numbers would help a bit. I am thinking that the engraving was dome sometime after the late 1950s up until fairly recent. It does have great eye appeal and and a good aged look. It is a very nice looking gun and most here would be happy to own it. I am sure more opinions will be offered.
