Hi! Im new to the world of straight razors. Recently I picked up an old genco razor from an antique shop. It was in rough shape but had quite a bit of potential. It took me about a week to remove the patina pitting and rust but I was happy to discover that the edge was pretty decent.

Anyway, I'm really enjoying the restoration process, but I can't find much information on how to date this particular razor. I've looked online and I can only find information on razors with the genco master barber trademark with two lines next to it, where as mine has three. This leads me to believe that it may be rare or not worth anything at all. Thanks for the help.
