This is very nice piece! It is an attractive Civil War 3.8 inch diameter Hotchkiss patent cannon shell. This is the Hotchkiss that used the brass paper time style fuse at the top of the shell. When it was fired the force from the blasting charge blew the fuse out but failed to explode the shell itself. That is why the whole top is blown out. It is very cool because you can see into the cavity of the shell nose. It is the pattern that was made with the flame grooves on the sides. The base cup is still present on the bottom of the shell. Most of the time they flew off of the shell when it was fired. As you can see the lead sabot flew off as well. The verbal history that accompanied this piece is that it was recovered from the area of the battle of Vicksburg, Mississippi. It would have been one of the shells fired at the Confederates during the siege. This shell is in nice shape and any artillery collector would appreciate having it in their collection.
