Here are pictures of an early version of the Zenith 1000 TO showing the
wavemagnet in place installed properly and upside down. Note that when it's
upside down, the red twinlead cable runs along the left side of the battery
box, just as you can (barely) see in the seller's picture.

If the seller's picture included just a bit more of the set at the top edge,
you would be able to see the wavemagnet.
