Please help and identify the maker of this EK2

Hi

I'd very much appreciate your assistance in identifying the maker of this EK2 that is in my collection.

With the little hump on the top near the ring I thought maybe Deumer but that's as far as I got.

Thank you

Jamie

**EDIT - Yeah it's a DEUMER** thanks for the help
