German 250kg sectioned bomb fuze pocket  with a 1940 cutaway (17) A Time Delay Clockwork Fuze & Zus40 Anti-withdrawal device


This is the latest item just out of my workshop, it is an original 250kg German Bomb Fuze pocket sectioned to demonstrate how the fuze was fitted inside the bomb case. The fuze is a type (17) A with an original gain pot, Zus-40 and wooden mock-up Picric Acid Ring & Pellets. Please see for sale/exchange section for the mock up Picric pellets.


The ZUS (Zunder Sperre / Anti withdrawal device) 40 was used in German WW2 aircraft bombs as an additional antiwithdrawal device, to be used under a normal fuze including the type (17) Time Delay Fuze. The combination of the (17) Clockwork Time Delay Fuze and the Zus-40 caused the death of many bomb disposal officers until on 2nd  September1940 Lt. Archer Royal Engineers removed a ticking type(17) fuze with the new type Zus40 Anti withdrawal fuze was discovered underneath.

Inert Sectioned Bomb Fuzes

For education & display

A large part of my collection is on public display at the Wings Museum, some of my items such as bomb fuzes, Butterfly Bombs, Shrapnel etc are used in talks to school parties at the museum. Sectioning a fuze is an ideal way of displaying a fuze so that people can better understand how the fuze would have functioned.
