    Hallo @FZG76,
    the LZtZ (17) Bm (Langzeitzünder=Long Delay Fuze) is a so called "Zerstörzünder"(Demolition-fuze) with a settable delay of 5-120 minutes. It was used in some special long range ordnance (like V1) to assure detonation of the warhead even if all other fuzes failed. Also it was used as a general demolition fuze where short delays, in the above range, were needed. As to your question about Bm and Am, I'm not shure, but think that they have different timing-ranges. I'll look if I can find something.

    Hi @FZG76,
    no, that fuze designation has nothing to do with the manufacturer. The (17)A fuze has a settable delay of 2-72 hours. They all used Thiehl clockworks.

    Yes, this is a Z(17)A with a settable delay of between 2 and 72 hours. The LZtZ(17)Bm that I have seen, had no markings on the body anywhere. I suppose that the "m" behind the "A"and "B" means mechanical (mechanisch) because most of all german airforce fuzes were armed electrically. These, only mechanically armed fuzes, needed to be handled much differently and had to be shackeled in, similar to allied fuzes. Also, our longtime member @PZGR40 has published a very good work about this same fuze in english. Attached is a page from the internet published by SKB company.
