I am curiouis how one overstamps a 25N Y to make it read 50B Y??
If none have been found where did the one I posted come from???
John Hudson, RE devoted an entire chapter to the 25B Y as he found the first one.
There had to be a 50 on John Howard's bomb but we will never know for sure without deduction.
Howard's bomb was immunized by the team who brought it to Erith Marsh, at least the 50 was.
so it was the 17 that killed him.
We were always taught that the '0' was a anti-disturbance/boob trapped fuze
If you were in the field during WWII how would you treat them both, knowing what you know?
The Germans were known for NOT mis marking their fuze heads.
So I guess I missed the question.
Below is the 25BY fuze, three mercury and one trembler switches to fire detonator
Best Regards,
John
