unknown (Handgrenade?)-Fuze

[Alpini]

I don't have any idea about the following item. The thread looks like seen on some handgrenades. The thin tube contains a rotten quick match.

Ideas please

Markings: E. B. 1 39

The ink stamps are very usual on french fuzes but "E.B." doesn't sound like any french manufacturer I have ever heard. Which country used ink stamps too?

E.B. maybe Ètablissements Billant?
