I will let the photos describe it further.
Here is a German marked (which I was told is an ICE Mine Fuse). This was given to me by a Sargent in the army who taught German Mines and Booby Traps ID during WWII. I believe it is quite rare. I in all my looking over the years have not seen another one. I have had it since the 1950’s. I have owned it for 78 yrs. It runs for 2-3 mins. There is a winding tool which is not original.
