Time Combustion, Direct Action Fuze, possibly German WW1

[AE501]

I have this Time Combustion Direct Action fuze but I do not know what it is.
The only markings are a crown, with a letter'M' beneath and '15' below that.
The time ring is marked from 4 to 42 with two marks either side giving 2 to 43 whatevers of range.
The only thing similar was a German WW1 type.
Sorry about he photo, I should have taken it in daylight.

Is very similar as the L.W.M.Zdr for the 7,5cm l.W.M.
But, if I'm not wrong, the M marking is for a Marine use !!!

It's a fuze for the german 6 cm. Spgr. L/3,4

Thank you silent night for the pointer.
I have found this in a French publication but I do not read French.
I think the gist is as I said but your info about the calibre is what it says in this publication, but I still do not know the number of the fuze

I don't think that there is an "official" name for this fuze.
It's just a Dopp. Z. (time and percussion fuze)

A belated hello and welcome to you. I have read a number of your posts with interest and am pleased that I may be able to help with this one. I have found a reference to it in the Naval & Military Press copy of the second edition of Notes on German shells, 1918. Following what Silent Knight and Yodamaster say, this fuze appears to have no name in that publication but was used with ammo for the 6 cm boat gun (page 6). Pages 286 & 287 note that the fuze is graduated in seconds from 2 to 43 (lowest and highest figures 4 and 42). Also that the 6 cm naval HE shell had a bursting charge of 0.13 Kg / 0.28 Lb of Granatfullung 88 (Grf 88)- compressed picric acid, in a millboard case and was fitted with a delay action exploder. The HE shell was employed `In trench warfare, against living targets at close quarters and against tanks; possibly against low-flying aeroplanes.' The 6 cm boat gun was rifled, with 24 grooves. Dz = Doppler Zunder, ie double action time fuze. The `M' stamp with the crown above was applied to all shells and fuzes of naval origin (page 35). By 1918 very few German shell had picric acid as the main bursting charge, TNT was widely used instead.

Further research in 'Artillerie Allemande 1918' P62 from downloads shows an exploded view of Z.S 26, upon which the organisation of the time combustion part is based. Even better on P29 it shows the actual marking with the crown above the 'M' (marine) with the last two date digits below that with explanation. All this is of course in French.
