    Kenneth Strickfaden "Megavolt Sr." Tesla Coil Used in Son of Frankenstein and Other Films (1930s-1980s). Coined by Strickfaden as "Meg Sr.," this was his personal favorite. Built in the 1930s, this primary and secondary Tesla coil is composed of a large wooden cylinder tightly wrapped in copper wire and a copper end cap mounted on one end. The primary coil is the thicker, insulated wire wrapped at one end; the secondary coil is composed of thinner, un-insulated wire. When powered by an external transformer (not included), this device can throw out up to a million volts of electrical energy in large, powerful lightning-like bolts. Meg Sr. can be seen prominently behind Boris Karloff "The Monster" in the laboratory sequences in Son of Frankenstein (1939), and it was used for electrical effects in a number of other films, including Frankenstein Meets the Wolf Man (1943), Abbott and Costello Meet Frankenstein (1948), and The Terminator (1984).

    Measures 48" x 16.5" diameter. Comes with the original cylindrical aluminum and wood transport case used by Strickfaden marked, "Tesla Megavolt r[eso]nator." Exhibiting age and production wear. In vintage Good to Very Good condition. COA from Heritage Auctions.
