wow ! i see before a clock timers , but never in original box Great !

These are "Zeitzünder für Sprühbüchse 37", mechanical time fuzes with a 1-5 min adjustabel delay.
There were not used for demolition work, but were fitted on the "Sprühbüchse 37", which was a steel cilinder containing 10 liters of Mustardgas.

The cilinder had 2 fuzes fittings, one on both end.
Fitted to the upper side (where the handle was), the fuze lit a small charge which ensured dispersion in the air, contaminating somewhere between 280 and 480 m².
The other side had a fitting with a detonator and small charge, which ensured 150 m² of contaminated soil after detonation.

I never heard of the Sp.Bü. 37 ever being used, but these fuzes are on the market every now and then.
But 4 fuzes in a box; that's a nice find.
Congratulations
