Those marks are from honest use, or I miss my guess! Maybe it could have been maintained along the way a little better, but if you could know where that Model 19 has been and what it may have seen and done along the way, I'll bet you'd be proud to own it! I carried one very similar from the sixties until sometime in the eighties. I would give a pretty penny to have it in my possession today, but that was not possible when we parted company. My copy was also obviously well used, rode hard you might say, although it was never put away wet! It was still as functional and dependable at the end of our tenure together as it was when it was first issued to me. Your copy has character, in my opinion, that can only be present when a gun has given good service! Congratulations for owning this one for what I consider to be a good price.
