From an ebay sale by Urfaust.
It was faded and I managed to improve the image some what and I was given this
description of use. "Rather rare picture of an old trench mortar from 1860' taken as a reply to the german Minenwerferand they were launching either à spherical bomb filled with black powder and using an old fashion
wooden time fuse ignited by the flame of the discharge... Or a wooden bucket filled with a lot
of old sphérical hand grenades lighted by the discharge "
