Can you help identify this razor?

Hi,

This razor turned up in my mothers sewing kit. I assume it was probably one of my grandfathers but can not be sure. On the front of the tang is stamped "42 SUPREMA" around which are the initials "S, K & L." On the tail it is stamped "FOREIGN" and on the back "4/8." It seams to be in very good order and once honed should work fine but I would be interested in any history about it.

Thanks.

Probably manufactured by R. Nöthen & Co. They used the Suprema brand as well as Ronco and Olaya. This one looks just like yours
