Found floating in the Bay last week - I poked around here & perused Mr. Razor but can't come up with an identification of this razor .. handle & head appear to be black, like PVD?
It's a slot handled ball tip Tech which was sold/distributed during the WWII era. It is painted brass. They usually came in black bakelite cases, but undoubtedly came in others, as well. Very nice catch! I'm envious.
