I now have two examples of the Glassmine 43 in my collection. I wanted to obtain one of these for many years, after first seeing on in a museum in Normandy in 1989.
The Glassmine was developed to be difficult to detect using the new mine detectors then coming into use with the Allies. There was not much metal used in the construction so they were hard to locate.
The mine was activated by pressure. The thin 1mm glass sheer plate would break, allowing the fuse to be crushed and thus setting off the mine.
There were two types of fuse used. The example here has the Hebelzunder44 or as it was nick named the "Boars head" pattern. Dated 1944 and maker code marked ‘GZX’ for "Schuco GmbH."
The glass bowls can be found with different mould numbers impressed into them and also the thick glass plates can be found in brown coloured glass.
The mine was useful being waterproof once the glass shear plate was sealed.
