I just took delivery of these two base fuses from two different sources. It turned out that both were still live, but that is no longer an issue. These have to be among the simplest fuses manufactured in modern times. They are very large compared to the space required for the fuse mechanism. Most of the space inside is taken up by the tracer element. They are interesting in that the detonator is what is held in place by the shear pin - not the firing pin as in most other base fuse types. I am not certain the aluminum gain/booster pieces are original - they are not marked in any way. It is also interesting to note that one tracer element is a very long burn and the other has only 1/10 the cavity size. One of these has a home in my 50mm APHE round. The other is waiting for a nice Pak 36 37mm projectile.
