Cosmo blade

[kilowattkid]

Came across this today during my lunch break. I stopped in a little antique store north of Dayton, OH, During a snowstorm, so the radio said. They were getting ready to close for the day (noon) and asked if I was interested in something particular. I said I was killing time and looking for shaving stuff, STR8's in particular. The woman took me to a case that had this and told me it was 20% off today, today only. I laughed a bit, checked it out and said why not.
I researched a bit on Cosmo blades and found only one reference on them. Other than that, nothing. It is German made. Any info would be appreciated.
As it sits I have only hit it with some #0000 steel wool and Mothers polish. I also put some laps on the 4K/8K along with some 12K. Not quite ready but should be soon with a few mild pyramids. It looks good but I have no idea as to what this razor is about. All info is welcome.
Thanks,
