Dating razors: British Hallmarks & sovereigns

[clavichord]

Investigating around my razors, I gathered some infos regarding british hallmarks, traditionally used by silversmiths. I realised that some hallmarks were also used by straight razors manufacturers:

Crown [City mark] = Sheffield (from 1733 to present)
Anchor [city mark] = Birmingham (from 1733 to present)

One more find (not strictly connected with silver hallmarks):

WR [sovereign's Duty Mark] = William IV (1820-1837)
VR [sovereign's Duty Mark] = Victoria (1837-1901)

Some examples (Wade&Butcher's in my gallery):

Pic.A (razor #11): [crown] + WR; very precise dating! The ebay seller of this razor published a pic in SRP some days before the auction asking info about the dating. Members agreed that it should be quite old (..the rust on the blade was supporting this opinion..).

Pic.B (razors #55-57): [crown] + V R;

Pic.C (razor #25): [anchor]; the anchor is sometimes used by Wade&Butcher but I don't know if this implies a relationship with the city of Birmingham; I couldn't find infos at this regard. "Sheffield" is absent in the mark on the tang, but this is quite common between W&B razors (very frequent among W&B "barber's use" blades). It happens that the anchor is also part of the emblem of Solingen.. eheh!
