notes: label: Description (Brief)
content: #7031 ceramic base rheostat with nickel lever. Two contacts, top swipe. Apparently the unit malfunctioned at some point. There are burn marks on the back, and the user removed the potting material and rewired the unit. Unit may have been made by Parken or Bunnell, see Greenwood-Clymer, pages 183-184.
