In an earlier thread started by me regarding a Nose Fuze No. 848 MK V (see: http://www.bocn.co.uk/vbforum/threads/102177-Bomb-fuze) I understood that the delay capsules with “Bickford fuzes” almost always were missing. I also have understood that the delay housed in these capsules varied. Does anyone have detailed information regarding the different delays and were these capsules marked in any way? All information is much appreciated.
