Hello, I'm new on here and would like to show some pics of a 38 that was my Grandpa's. After doing some research to locate the model number I found it to be a 10-5. I would like to know what year it was made, googling info didn't help much. Also I don't see many nickle plated with 2" barrel 10-5's so is this a rare model? Thanks to this forum I found that what I thought to be a crack isn't a crack, I attached those pics also. I would like some opinions as to the shape and possible value but I don't want to sell it. Thanks all.
