This leyden jar/electrode combination has an adjustable gap with a micrometer-like adjustment. The maker is probably Max Kohl, as a nearly identicle one is pictured in the 1912 catalog. This is missing what appears to be a wire that sprials up the glass support to the left as well as a solid wire that connects the base to the adjustable gap. The holes for these wires are visible on the base and gap electrode. This device might also be called a unit jar. | |

The gap is adjustable through 2.3 centimeters with a precision of .02 centimeters. |
The electrical contacts to the inside of the leyden jar are made with three brass legs. |
