    I own these things and got them from a an old guy, now since gone from earth, but i know nothing about them or what purpose they served or what to call them, even. Both are heavy, with the larger one being extremely so, like 20 lbs or more, maybe. I cannot imagine what is in them to make them that heavy, can you? And then there is the coil unit.
    Sure would appreciate any of you short wave guys giving me the lowdown on what these are. Thanks.......

      The two large heavy things are "transformers" -- they take 110-120 volt current from the wall outlet and turn it into various other voltage levels, to power other sorts of devices. They are full of mostly steel and copper with the rest being black tar 'goo'.

      The coil thing is most likely an 'element' to be used on an antenna, intended to emphasize reception of a certain narrow bandwidth of radio transmission.

      Hope this helps -- the googles will be your friend with lots more crazy specific info about all sorts of types of both these things! :-)

      Hey! THANK YOU. That is a start, anyway. Really appreciate your input...

      The one on the left is marked with Navy symbol.

      The coil appears to be a dipole antenna loading coil.

      THANKS, Dave. I should bought the radio, too. It was an oldie. I did get about 100 pill bottles, each full of tiny transistors of different capacity and a box full of crystals, that plug into the radio, i guess, for different frequencies. Wish my head went more in that direction...looked like fun.

      The crystals are easy to sell..but haha..my dad was into Ham radio and electronics for 50+ years. I'm talking thousands of everything. He also taught Ham radio license and electronics classes in the basement. I still get 2 tables every year at the electronics swap meet..

      A small glimpse of what I've been dealing with for last 14 years...

      Your pop was into it, for sure! I did some photo work for a guy on the island here, who's dad left 5 large WAREHOUSES full, (like your photos) of years worth of radios, phones, car radios, tubes, electronics of all types, televisions, original manuals and you name it. Stuff went back to the early 1900s. He had filled and hauled off 12 large dumpsters before I got to him to let him know that it all had value. I documented several hundred old radios/phoonographs from the 1920s thru the 1950s. i still have nightmares about him throwing all of that into a landfill...

      Yeah unfortunately the younger generation isn't into fixing stuff and prefer solid state. And as more Ham radio folks get older, the market is flooded with their estates. So prices have dumped. Can hardly give stuff away.

      Dad had a huge manual library that we donated to the local radio club. Again...everything is on line and can be downloaded, so value is almost nothing now. I gave the scrap guy 1200 lbs of transformers.
