Questions about German fuze pockets

[pzgr40]

I have this loose German fuze pocket, it is 325mm long. I want to place a Time fuze 17 in it with a ZUS 40 below it and change it to a cutaway model. Below that there are blocks "picric" as I read in an US manual, however I suppose it will be TNT.
My questions: What is the length of these pellets? And are they packed in paper like the Brittish pellets? Who can help me on a drawing or sizes.
Was it also used in conjunction with the ELAZ 25? According to a German description on the EEODA site it was done, but I assume this has only purpose if the bomb is released with the fuze not -electrically- armed to form a booby trap, as the ELAZ25 is an instantanious fuze.

Thanks in advance,
Regards, DJH

Both explosives were used (Grf.88 and Fp.02). and they were wrapped in waxed paper. The length of the charges depend on the type of the fuze pocket. So you need to do some research in which bomb your fuze-pocket was used. A SC250 for example had block lengths of: 1x37,3 (Ring), 6x30 mm (solid). Older SC250 types had different block lengths. May be your pocket is from a SC250.
