What is the difference between these two razors? Mosty I see the Imperials for sale on Ebay. (I have a NOS Imperial, that I have not used yet.)
The Imperials have three rows of greek key markings on the lids, whereas the Viscount has 1.
The Viscount also has a more rounded corner case than the Imperials.
Some differences in case materials over time, but the innards are basically the same.
