Seller: firebottles (3,594) 100%, Location: Chapel Hill, North Carolina, Ships to: Worldwide, Item: 192704724132 I think it's safe to say that if -- after checking out all my listings this week -- you can't find anything that interests you, you either aren't really looking, or there's nothing in the world that you find interesting anymore. I've put together an excellent and diverse assortment of mechanical, technological and musical antiques, and regardless of how eclectic your tastes might be, I think you'll find something you like. Here's a century-old electro-shock device that looks like it could have been pulled from the set of Back To The Future. Perhaps it's some early iteration of Dr. Emmett Brown's infamous flux capacitor. If you look at the photos, you'll see, in the upper right hand corner of the chassis, a small motor secured by several metal brackets. The motor is powered by the same batteries that power the induction coils and its speed is regulated by a cylindrical rheostat mounted in the upper left corner of the chassis. The shaft projecting from the right side of the motor's armature is coupled to an interrupter that regulates the frequency of the current. The shaft projecting from the left side of the motor's armature is connected to a cylindrical worm gear that drives a circular reduction gear, which in turn rotates a primary coil, the speed of which, as it revolves in one direction or another, determines the duration of the peak shock. To the left of the primary coil is the secondary coil, whose proximity to the primary coil limits the intensity of the shock. The distance between the two coils can be adjusted by the rack and pinion assembly whose black bakelite control knob is mounted on the end of the vertical shaft just forward of the the two coils. It's as simple as that. Condition is very good throughout. All parts appear to be original, and the cabinet's wood finish is original, with only scattered marks consistent with age and authenticity. The carrying handle and its associated retaining clips are missing. Hardware all appears to be original. Motor, rheostat, levers, switches and coil windings are clearly original, and they're clean. Original paddle (there's only one), original battery wires inside the battery box. I can barely understand how this device works, much less how to hook it up to a bank of batteries, and therefore it is being offered for historical and/or display purposes only, with no assurances as to whether or not it can be made to work in the manner that its evil genius inventor originally intended.. Measures approximately 12" x 10" x 8". Shipping weight approximately 25 lb. That's about it. I will pack it carefully and properly.

Here's the workaround. If you click on my feedback score, you'll be taken to my feedback page. There, on the right side of the page, you'll see a link that allows you to "view items for sale." If you click that link, you'll see everything that I currently have listed. Alternatively, if you click my seller name, "firebottles," you'll be taken to my seller page, where you can also view everything that I currently have listed. I apologize for the glitch. I'm trying to get it resolved with ebay.
