A couple of years ago, I and a friend recovered an unexploded Hotchkiss shell from a river in the Southeastern United States. (Yes, we did so legally with permits.) Since that time I've wanted to preserve it but had not found the time to do so. I did finally find some time over the Thanksgiving holiday.
One of the joys of recovering old relics from our Nation's past is the satisfaction one gets in preserving these artifacts for future generations. Below are the results - before and after.
