The patent on the larger Frays with the wing nut style locking mechanism on the front are from August 7, 1883. I saw them listed in theor 1911 catalog as their patent hollow handle tool sets. I don't remember if there is a patent on the smaller one, it is the only one I have come across like it. It is also in the 1911 catalog as the Combination Haft. in Cocobolo or Maplewood handle.
