Generic "Solingen" handle from the 30ies and upwards. Can be whatever is stamped on the bottom of the handle or onto the box. Pure zamak as is the head.
For eg. ROMI:
I was digging for some information about a couple of vintage razors and I came across these pictures. As soon as I saw the handle, I knew it was the same razor. Some describe it as ''rare'', but I'm not sure how rare would a zamak razor be.
