      Sideswipers and Vibroplex keys were two different type of keys.

      The Bunnell Double Speed key was invented and made in 1888. It was a
      different design of a telegraph key which was worked side to side with
      a single lever, double contact. points on either side. The motion was
      side to side with each side completing the circuit. Both sides were
      used alternately and the operator was responsible for lingering while
      making the contact to form the elements of the Morse code.

      The Vibroplex key was invented and made in 1905, by Horace Martin.

      Both keys were made in New York City - the hotbed of commerce and telegraphy.

      A Bunnell Triumph straight key and a Bunnell sideswiper - I think by
      1905 both varieties of the double speed key - including the often seen
      "Type W" which has adjustable tension were available, the Triumph most
      certainly was an it was the design that first used a steel lever which
      wouldn't bend.

      Someone on the morsecode@... reflector would be more knowledgable than I am.

        If it's a genuine Bunnell Double Speed, they seem pretty rare.
        Actually, ANY sideswiper is pretty rare. They could probably sell it
        and fund the purchase of several keys of the type they need.

        The Bunnell Sideswiper came out in 1888 - the Vibroplex in 1905. 73 DR
