This is the tuning gear inside Building 42 that was originally used with transmitter BL-10. Note the corona ring around each coil, and the "walking beam" type frequency change switch between the two coils. These are actually variometers as there is a second rotating coil inside each one that can be remotely adjusted by an associated selsyn.

In this closer view of one of the variometers it is easier to see the selsyn that drives the inner coil (the selsyn is the cylindrical object with the red band around it in the lower right part of the photo) and its linkage.
