I recently picked this up in an antique store. First time I have come across one of these. Not much information available. The Compendium of Safety Razors has two references for Kenyon Safety Razors...one Kenyon in New Haven Connecticut and one Kenyon-Silvar in New York. Both described as single edge razor, open comb with a flat metal handle. Dates are uncertain...one says early 1920s. Anyone have any information on this razor?
You may try across the street, may be someone who knows there. Also, perhaps a post over on the injector and SE board.
