Thread: What can you tell me about this F.A. Koch?

Greetings gents, I'm new to SRP and have a quick question.

I spotted this little gem at an antique mall the other day and decided to go for it. Being familiar with the popularity of the F.A. Koch Faultless razors, I figured I'd get home, google the Cyclone, and find a bunch of info, or at least some stuff on Koch that would lead me to figure out what years these were made, but there's almost nothing out there on this razor or on the company besides an un-cited claim that "F.A. Koch knives were made from 1874-1933". Can anyone point me in the right direction as far as digging up some info on what years these were made and/or any other legend and lore?
