Fuze type please?

[Millsman]

Can anyone let me know what this is and how old it is?

Thanks

Unknown fuze

first idea, it's a mechanical time fuze.
Have you dimensions, other markings,...?

I have one of these marked L81A1 INERT. I also seek information, especially a how-it-works diagram. Here are some pictures.

Thanks for the photos. It looks to be a terrific piece of engineering for a use once item. Mine is only marked D67. Otherwise it looks to be identical.

Overall length is 98.8mm. Diameter at thread 38mm. Base of cone diameter is 61mm.

From the information i have The Fuze is the L81A1 or L81A2 used on 105mm illuminating L43A1 and L43A2,It is a modified version of the swiss designed Fuze Time D1X1 type 502-EN-5.It has no impact or graze facility and is mechanical time only

So if FOO31's has L81A1 on it and mine has D67 can I assume mine is Swiss? If so is it rarer than the UK variety?
