Elaz (55)

The ELAZ (55) is a good example of later war development. By using thin steelplate instead of brass or aluminium castings for the body, the price dropped to a fraction of the early models. But, for the collector this means that ground finds are just rubbish after 70 years, completely corroded, like yours. The (55) was ment to be used instead of the (25). What else do you need to know ? Attached is a original drawing made by the inventor himself in 1946.
Greetings,

Many years ago I got an ELAZ (55) in even better condition than yours. I wanted to make shure its inert. When screwing out the brown inner plastic ring with the 2 round keyspots (left turn) in the bottom (your 3rd picture)and removing the remnants of the parchment paper disk, there appeared a rubber-gasket-type black ring below. It broke when it was taken out. The appearance is a little bit shiny black, not the opaque black of rubber. It burned with a electric-spark effect and near to smokeless. I assume this to be the elusive Tetranitrocarbazol that was developed during the war to replace Black Powder. Upon ingress of moisture the Sulphur in BP reacts and Hydrogen is produced. The interaction destroyed the Prime Ignition Comp's. Tetranitrocarbazol was the remedy to this problem and was first used in signal cartridges. I have no comparsion, as I have never seen Tetranitrocarbazol and how it burns. I also have not seen any literature delving into this fine pyrotechnic points in ELAZ of delays and relays.

I can only confirm :
from "Liste der fertigungskennzeichen fr waffen, munition und gert", Berlin 1944

bw = Minerva radio, W.Wohlleber & Co, Rundfunkapparatefabrik, Wien 62, Zieglergasse 11.

Hi, Please see my collection on the link below, scroll down to the 55. My one has a wire coming out from the side which would have attached to a nose switch, I have this down as being used in the SB1000, quite rare in good condition.
