This pistol has been in my family since I was a boy and I am 78. I would like to sell it or trade towards a new pistol. I have never fired it and do not know the caliber. I hope the pictures show up. Please give me a value. The grips are a trifle loose. The action is tight, it cocks nicely, and trigger pull is crisp. I am not sure if I can legally mail this and would go to local Cabela's to see about trading. All advice appreciated. Many Thanks
