Howdy, Just picked up a 7 day set that is in excellent condition as far as the razors goes. On the blade it says "Aquila gold" & caschmiso. The other side says richard schmitz solingen. I've found out very little other than there is a man who has the same set and he is missing the "tuesday" razor. I'm excited, i never thought i would own a 7 day set!!! Of course any info would be wonderful, thanks for looking Also i'm scared to clean them up because of the red and green...what would you use for very light cleaning that wouldn't hurt that?
