Hi. I have a Wade and Butcher straight razor that does not say SHEFFIELD or have any service marks but it only says:

M A N U F A C T U R E D B Y
W A D E & B U T C H E R
F O R G E N T L E M E N S U S E

It has a black bone or ebony handle. i was reading somewhere that it may be pre-1830. Can anyone shed light on this razor?
