The Kampfe Star safety I won on eBay for $45 came today. The dates on the bottom of the head read: "Pat. June 15, 1880. Engl. March 8, 1887." It arrived loaded with a wedge blade. I'm assuming it can't take regular SE blades, but I just want to confirm with people who know more about these things. Pics (pre-cleaning right now, I'll clean it up and post more later):
