Can someone give me approximate Date/History of this W&B

[Chefbaze]

I just picked up this W&B 7/8 The Celeberated Hollow Ground...Its in great shape, no rust, pictures show glare, that looks like rust...All Ive been able to find so far, is being that it has the "Sheffield, England" Stamp on the tang, it is post 1891.....Other than that, Ive received mixed opinions...a friend told me the scales aren't original, that the razor was made before W&B changed the etching, and at that time they used only horn and these are celluloid...Someone else who restores razors said, the Scales are all original Bakelite, which make sense for that model/time etc.....2 different takes altogether....So, Im trying to get a concensus here, as to its approx age, and if its original......My gut says theyre original..Most rescales Ive seen, look a heck of alot fresher, and newer than this...And the seller wasnt really a razor guy, just an antique vendor....Anyhow, Id love to know more about this razor..Im excited to have it..Ive wanted one for a while, and finally found one that called my name...Regards, BP
