After reading this thread, and seeing the pictures, I am a bit confused. What I understand is that there were two different fuzes, a Langzeitzünder (17)Am for aerial bombs, and a Langzeitzünder (17)Bm for demolition. Correct?
If so, are all the red fuzes shown above the Langzeitzünder (17)Am, and only the green one shown by millsbomber is a Langzeitzünder (17)Bm? Or are they both identical from the outside?
Also, did the Langzeitzünder (17)Bm still use the same set-up with the gaine like the Langzeitzünder (17)Am aerial fuze used, even though it was being used for dempolition?
