German ersatz case

[Collector56]

Another 7,7cm bimetal case has arrived
This one has a different maker than all the others
Does anyone recognise the "E&G" maker?
I can't find any mention of them in any of my literature.

it's Ehrich & Graetz:

They also made small arms ammo fuzes and probably a lot more war releared products
