A real gun. 22 cal, 8 shot Beretta small pocket pistol. Beretta started making these small pistols in the 1980's. Found in the river, 12 inch deep water, no mud, river has a solid red shale bottom. There is a main bridge not far upstream and a high crime city full of unsavory characters. And so I think the gun was thrown in the river from a car. Last month in the same general location I eye-balled the Valentine & Bro 50th anniversary ceramic paper weight on the sand bank. The company went out of business many years ago. Will search that area again, many small pieces of very old pottery can be seen laying on the bottom of the river. A 1700's mill was located a little further upstream, somewhere. Jabbo
