2365 An old "Clicker" television remote.
2367 Looks like a rail car wheel.
2368 For pop rivets?
I agree. Unless there was an IR version back then -- or even a
visible red LED version. Visible red ones apparently started in 1962,
so it is possible -- and they might have used the same case for both
styles of clickers.
And the IR ones in 1961 -- all according to Wikipedia.
Or -- it is possible that the afternoon sun heated the circuits
up enough to switch the frequencies which they responded to, so they
could not "hear" the tones.

Hmm ... and Zenith was the actual TV which Heathkit provided in
kit form IIRC.

Since the RC airplane was typically too far away for an acoustic
remote to work anyway. :-)

My favorite trick at that time was to walk into the room shaking my
ring of keys.

Or drop change on a bar while the football game was on. ...but don't expect
to be served after.
A clandenstine PDA in a bar during football might get one
pounded, or pitched out.

Particularly in this part of the country.
