I believe the change in the letters after 25 indicates internal modifications usually a change in a resistor that can either delay or lenghten time it takes to arm the fuze or to fire the fuze.

The (25) B can be used against Sea and Land targets.
Repleaced the (25) A* and the (35)*.

 

[Fuzeman]

Thats correct guys the difference between the A and the B is internal changes, the (25) series fuzes were generally used for land targets and the 8 series ie (28) were for hardened targets Ie Shipping use .where a delay was required to enter the ships deck before exploding .
See Fuzes a laymans guide sorry i cant work out how to put in a link on here

Thanks guys for the info.Does anyone have a 25 with the Y intead of a date in their collection? Ive read these were made to decieve Bomb Disposal crews ,Dave

 

[Fuzeman]

Dave Does the fuze look longer than the normal (25) series and is it wider at the bottom if not its a normal (25) series fuze the y being batch letter?
A picture would confirm this!

Thanks Allan happy new year ,
Sorry we lost another sapper from 33

Hi Fuzeman ,i havent got a 25 with the Y marking ,i was reading the Bomb/fuze section in The Blitz ,Then and Now ,Vol 1 when i came across a reference to 25s marked with a Y instead of a date that were made as anti-handling fuzes by batteries and could remain armed for a year .I just wondered how rare these were and thought i would get plenty of assistance from members ,regards Dave

Hi Dave
Up to a few weeks ago i would have said that their wasnt a german (25)Y fuze in exsistance, they were all (50)B Y , but i was shown a xray picture of a (25) Y taken sometime in 1940,s Clearly showing the marking (25) Y .
the first y fuze immunised by using liquid oxygen was carried out by Prof John Hudson, he still had the original fuze , which when we looked at it was actually a (50) B y of which i have several in the collection, john was as surprised as i was , it was he who produced the procedures for extracting these battery operated fuzes.
I have never actually seen a real (25) Y only (50)B y ,s

 

[Big Dave]

Thanks again Steve i had never heard of the 25 Y until i read the book ,i was just checking wether id missed something ,regards Dave

Hi guys.
EIAZ 25 Y it's possible. Look there.
Fuzeman you have this book, look there info about Y fuzes.

[Fuzeman]

Hi Alex
Yes i have that book , , nobody in bomb disposal who handled the y fuze either in bombs or instructional courses had seen an actual (25) they are allways no (50)B y , i thinking is that when John hudson first removed this Y fuze he wrote in his original report that it looked like a (25) and from that report it got corrupted into being a (25) instead of (50)B Y .

Hi Steve

They are all 50 B Y but they have many different markings. It can be marking EI.AZ 25 B, EI.Zt.Z 9 A and I thik possible other too. In Russian WWII manual Russians wrote: If you see a letter Y after CPP on the fuze body, don't move a bomb, because it's a anti- disturbance fuze.

Hi Alex
Ive never heard of a Y fuze with the markings of a airburst type (9) series fuze
The German manual L.Dv4200 only lists the markings for the y fuze as (50)B y

 

[waffenamt]

Steve,
I believe there has been a lot of confusion in the past with the letters 'cpp' followed by a 'y' on type 55 and 9 fuxes but am sure the 'y' in these cases are only batch letters?

Hi Paul

Hear is the said article that has had a few people confused over the letter y and this is why this one of mine is in the nude:tinysmile_twink_t2: nay mercury switches to be seen.

Best phil

I could be wrong, but seem to remember reading somewhere that the Y stamp mean't that some modification had been made to the fuze. ie a type 55 with a Y marking would be a modification of a type 55 without the Y marking. Maybe just a minor difference- not sure.

Thought it worth a mention, anyone else heard of this modification theory?
