I have another question. There is something I don't understand:
Most of you know the page Straight Razor Manufacturers and Dates of Operation
It says:
WADE & BUTCHER
Successor to Robert Wade; succeeded by Butcher, Brown & Butcher
Sheffield
1818-1890 ("Old Sheffield Razors" by Lummus. Antiques, December 1922 p.261-267)
and
WILLIAM & SAMUEL BUTCHER
WADE & BUTCHER
Eyre Lane, Sheffield.
circa 1845 to at least 1919
1830 - ? ("More Old Razors" by Lummus. Antiques, May 1927 p.372-374)
So, did W&B produce razors till 1890 or till 1919?
