Induction Coil I do not know what this was used for, it came as an unexpected part of an auction lot. It appears to be part of some larger apparatus since only the front and top (as shown here) of the unit are polished. The ebonite panel is stamped "REG.No.381 No 7988". Adjacent to the C terminal is an ellipse enclosing what looks like 8TH. The windings are encased in a solid block of wax and are continuous. I still have to experiment to find out how many volts are reqiured to get it buzzing.
