I have recently obtained this fuze plug which I'm looking to identify. It is solid and heavy but not metallic. I am assuming it is a Mazak / Zamak type metal. The finish looks to have been rough cast with the pair of key holes at the nose. The thread is typical of first war German fuzes and it easily screws into a 7.7cm shell. The only fuze that I have that is roughly the same profile with nose keyholes is a Krupp fuze in the third picture, but I've no idea if this is a match. The paint in the depressions appears to be a sort of grey but I don't know if its original.
Can anyone identify this plug? TIA
