Ooh! A dual stator 360pF air variable!
What's with the Morse code chirping in the background ?

OMG very few could identify that as well as it's C, my detector says radio tendencies haha
Next on guess that part is a 455KHz transformer
Yes, part of the LO & Mixer circuit to convert to a 455-kHz IF which was common in the classic 5-tube superhetrodyne AM receiver. ;-) They were everywhere, at least here in the U.S.

I remember playing with them as a child, but they didn't hold much play value beyond curiosity.
so, yes, they were everywhere.
I wonder if it will slice cheese.... several slices at once ;-)

Brings back fond memories, i got a Allied Radio knight kit 5 tube radio kit as a kid and had a hallicrafters S-38e short wave next to my bed which was the standard 5 tube radio but had a switch to change the coils so it was .55 to 30MHz.
There is something about old shortwave radios
I had the Hallicrafters SX-71 on loan to me from my uncle. If I recall correctly, the radio had the shortwave bands on the left and wider and more precise tuning (band spread?) for the Ham Radio bands on the right. It was meant mainly for AM & CW reception but would pickup SSB with the CW BFO turned ON and adjusted.

Lucky kid! That was one of the radio's I longed for, a classic like the sx42.
I bought a 71 to restore a couple years ago but have not gotten around to it.
It turned out about 15 years late, that my s32 was way out of tune and actually was better than it had seemed sigh..
