Wow!
Also shown is a ‘ferris wheel solder bath’ that is exactly both of those things, a ferris wheel and a solder bath:
OK now that’s crazy – you have to see it in action!
Some other fun facts about the TR-1:
The unit sold for $49.95 in 1954, which translates to ~$445.66 in today’s dollars!
Approximately 140,000 TR-1s were sold, proving there was a market for portable transistor radios – even at that price.
The radio required a battery about the size of a 9V but which was packed with 22.5V!

I believe that’s a TO-22 transistor case.
