Interesting mashup of the VC2 blade holder and the VC4 solid bar guard. I've seen at least one photo of a differently-branded Japanese AutoStrop knockoff, but I can't remember the name.
UPDATE: - Found it, "Bon Maeet", a VC2 copy. And then there's the "original" Feather copy too.
I like to switch between my double-edged Esso my Sinclair single edge razors....just kidding....a little gasoline humor!!! It is a really interesting find, thanks for sharing!
