My dad remembered he had this stashed and pulled it out for me. It belonged to his grandfather and said he remembers him using it regularly. I'll be picking it up from him shortly but wanted to get some info if I could.
It appears to be a Crown and Sword.
Ern is a well known razor brand that started around the 1900 but made razor for many decades... Operating out of the wald borough in solingen... Known for their crown over sword maker mark... Although your version isn't super valuable it should be a suburb shaver and considered a major brand of the time
