My opinion (take it for what it's worth..very little..lol)
The razor looks like it was made by an individual. By that I mean, not a company ie: Wade & Butcher, Wostenholm, ect..
To me it looks like a one time deal (much like a custom maker today).
The tang looks like it may have been forged (hammer and anvil) and the grind is different then most I've seen.
The shape itself is pretty straight forward, all straight lines or very little curve.

No doubt it's a interesting piece
