Found today in the wild, 1930 New Big Boy Chromium De Luxe. As a added bonus, the blade bank was full. It contained 7 Blue Blades and 7 Kro-Man blades. All are unwrapped in good condition. Never saw Kro-Man blades before. Some google-fu told me they are quite rare. Looking for some info on the blades so I can treat them with respect they deserve.
