The family and I were headed home after a big ZERO at a large antique mall and I decided to stop and get the times for another shop on the way home (I had passed it up on the way to town) thinking they were already closed since it was 5:45 PM. Turns out they were open till 6PM and I had fifteen minutes! I quickly scouted the locked cabinets and found several things, including a Signature Single Ring. I thought it was a regular Single Ring and didn't realized it was a Signature till my daughter and I was cleaning up the haul. I have only heard of these before (only because of Achim's gallery) and I started to wonder -- what is the story on these? Has anybody ever come up with anything firm on why, when and how many Gillette made? This one is a serial number A389083 which makes it a 1908.
