Jason Clarke Antiques has dated this piece to the 1850s.
Comprised of a glass handle with brass shaft and hinged tongs with discharge spheres at each end, these interesting and quality examples would have been used in conjunction with a Ramsden, Nairne or Wimshurst type electrostatic generating machine as a hand held method of discharging the spark created during use.
Rare to find these early examples and of such quality.
