Would Hans Rohmer use Neu Ulm and Munchen on their labels or maker marks?

Aren't they two different cities?

I have heard of the Neu Ulm Rohmer as a supplier of military items, like belts and the helmets pictured here.

I am looking for the existence of a Hans Rohmer from Munchen who supplied fire bayonets.
