It's a fake.
It is a well-known reproduction , not even executed in the correct material .
Here is a an identical fake , please note the irregular pebbling on the surface ..
Now compare to the smoothness of an original .
Reverse - look at e.g. the finishing of the rim , compared to the crudeness of the fake item ..
As for the name of the maker 1194 , the marking indicates a direct SS contract - and to my knowledge this one has not been identified .
We do know that they recieved a similar contract in 1939 ;
Front is identical - originals ( always in Aluminium ) of these are harder to find than e.g. the RZM 63 versions .
Note again the smoothness of the pebbling ..
And finally in 1941 - a contract for plain pebbled tunic buttons ..
