19th century J.A. Henckels Sterling Silver Straight Razor

other side:
Kent & Stanley Co.
From what I can find, Kent & Stanley was a manufacturing jewelers which went under in 1897 (source: New York Times). My guess is that the razor was either made for that company or that Kent & Stanley made the sterling silver scales. Either way it is most likely that this razor predates 1897 and by the looks of the leather case that seems very likely.
