Thanks for the response! The heel method is finicky for me, as a Greaves pre sheaf works has a nice heel. I have read the tail length method is the better indicator. But only for Sheffields, french blades don't fit that mold. And then there is the fact that it appears to lack a makers mark, hopefully once I get it I can distinguish the maker. I am hoping that someone has this razor tucked away in their collection.
