WW1 TUNNELLERS EXPLODER, 1914

Used during WW1 by Tunnellers for generating enough power to fire the detonator used for High Explosive, when the plunger is pushed down it turns a generator which supplies a high voltage necessary to travel the long lines to the charge.

AUSTRIAN SCHAFFLER 355 EXPLODER AND TEST METER, 1955

Exploder used to set off a detonator attached to an explosive charge.
By turning the handle the unit generates a high voltage which is sent to the detonator installed the charge. The meter is used to test the circuit before firing. Using copper wire 50 shots are possible (Detonators)

WWII SOE TIME PENCILS

Time pencils were fuzes timed by acid corroding a thin wire , when the wire broke a spring forced a pin onto a percussion cap exploding a small charge.

Timing could be erratic in different temperatures, a colour code denoted the time period of each fuze.

Used mainly by resistance movements in various Countries.
The items shown are colour time code Green.

WWII DEMOLITION TEST EQUIPMENT MK1

Unit used for testing detonator charges when using thin wire as a means of ignition, the wire would be fixed between two pillars and the current increased until the wire burned out, it then had to be calculated what charge would be needed to rupture the wire when surrounded by an explosive substance and ignite it successfully. The unit can 'Check continuity of the ignition circuit' 'Find resistance of a circuit' 'Test for fusion resistance of the wire' 'Test the battery in the unit'.
