Fuze ID please

[Burney Davis]

I have attached below a couple of pictures of a German fuze. Can anyone provide an ID and advise which projectile it would have been used with? The graduations are 4 - 56 and the only markings are 'Kr 12' and '8'. I assume this is a Krupp fuze and the date is 1912.

Thanks in advance.

Many thanks Minen. It did come as part of a mountain gun round, so nice to know it’s ‘right’. The only line drawing I can find of this shows the graduations starting at 1 - is there more than one mark or model?

Some old documentations show diagrams with graduations starting to 1 but I only saw this fuze with 4 for first graduadion.
(could me made full brass or mix Brass/zinc alloy).

Designation is "Dopp.Z. S/29"

but the scale goes until 56hm (5600m)

Not to confuse with other S/29 fuzes, there are some of them. Krupp designations are not unique.

I have always known this as Dopp Z 56(or S56). Mine is also graduated 4-56.

Hello Richard,

The 56 are hectomters. The "S" like in the well known S/43 is the physical sign for time. But you can also call it Dopp. Z. 56hm. Most Krupp docs use the S/ writing and also German Military documents. But I also have seen the hm writing, maybe in norwegian docs.

Hello. If I can give my two cents, I think that the mark below 1912 is not 8, but З, that means [FONT=&amp]запалка, fuze in Bulgarian. [/FONT]

Hello,

no, it's number "3". I know several examples with different numbers. For example: Kr 4 / 2. And all bulgarian fuzes with "Krupp shape" I know, have a small hole in the top cap. I guess for the fuze setting key.
