The Base Fuze Mk 134 consists of a molded plastic case in which a length of Ensign Bickford safety fuse is coiled with a cap on one end and a 20 gram charge of black powder on the other.
Blast from the motor impinges and fires the cap. The cap sets off the fuse which burns for 15 seconds before the burning gets to the black powder charge. Explosion of the black powder expels the window load through the forward end of the rocket.
No information about hazardous components.
Nothing else to see.
