Unknown fuze (?) key

[Mannlicher]

Hello everyone.
Quick question for the colective mind - is this some kind of fuze key and if so, for which one?
Found in mixed austrian-russian zone.
Thank you în advance.

Hello,

it's called M.5 Schraubenzieher (M.5 Screwdriver). It was used for the filling plug (Glycerol) of the recoil brake of the 10 cm M.8 and M.10 mountain howitzer. Possibly used for other guns too.

That is MOST impressive I have to say. Your knowledge of German ordnance is just breathtaking. Keep up the good work.
