Here are some higher resolution images of the
R5223 Reception Set.

Top view. You can see the two i.f amplifiers and the detector agc unit have had their original coils removed and replaced with transistor radio coils. This has worked well. never attempt to adjust the original coils, they will just disintegrate. You can see that every sealed can has had to be opened. They were only soldered shut, a stout knife and chisel will will removed enough can to get at the components.

This awfull paint job was not mine ! Underneath the original still is intactSo, you want to restore it ? Be prepared to open every one of the sealed cans The metal plate upper right  holds all RF unit coil slugs. It rides up and down to fine tune each band over its one megahertz bandspread. This a superb acheivement or micromanagement at its worst. However, the extraordinary sensitivity or this radio speaks for itself....when it works!
A view of the detector and AGC unit with my Hamification, a ceramic resonator, required after I attempted to adjust the original coils resulting in their destruction.
My replacement IF transformers, a pair of transistor radio IF cans connected back to back mimics faithfully the charateristics of two hi Q coil resonators. Gain was not lost by doing this.
The front panel shafts can be disconnected by removing the little retaining ring
first mixer oscillator crystals next to input RF unit. Each of these must be unsoldered to remove the RF unit for serviceSelenium rectifier for negative AGC bias.
There is a spare spool of nylon fishing line in case the dial cord breaks
