Description: | Stofskreis Variometer (engaraved in the end cap and picked out in white) Glasgow University Campus, University Avenue, Gilmorehill, Glasgow G12 8QQ, Scotland. On surface MANU unknown for the German Wehrmacht (armed forces) Luftwaffe. circa 1943 unknown Germany This end cap was part of the variometer housing of a type LMB German parachute mine. The variometer was designed to detect the magnetic field of passing ships. When the field strength of ship was sufficiently large the bomb was detonated. In general the larger the ship the greater it magnetic field. The sensitivity of the variometer could be adjusted by rotating the core of the twoo series connected coils that comprised the detector. N.B. During WW2 all shipping travelling up the Clyde was degaussed by a loop of cable carrying a large alternating current that destroyed the magnetic field of the ship. It was placed between Stinking bay on the north end of Great Cumbrae Island and Bruachag Point on the Island of Bute. This object was found by N.M. Dewar Gibb the son of Professor Andrew Dewar Gibb, Regius Professor of Law at Glasgow. Mr Gibb collected it in his youth as a trophy during the Second World War. It is one of several pieces found near the University flagpole above the river Kelvin - see also C.1984.18 to C.1984.21.
