This weekend I was passing through Mobile, AL and stopped to see a friend. He had quite a number of interesting shells but this one thing I found really interesting. It is a 24-lber Landmine that was made with a polygonal cavity. There is no real way to know if they converted a 24-lber polygonal wood adapter shell (most likely) or made it as a landmine from scratch. The first image is of the frag showing the fuse hole and the side loader plug hole. The second one shows the frag with a fuse sitting in the fuse hole. he didn't have a plug to put in that threaded hole. Very neat.
