I'm not a razor expert, but was curious if anyone had any insight. If I had to guess on age I would say mid 1900's? It was found near that super rare wheatie today (lol).
I used to shave with one of those. You turn the separated part of the handle(the end of it) and it opened up the razor compartment. A close shave with those oldies. Mine was not that old, they made them for many years.
