I do have the front panel, which cleaned up nicely...but no knobs.

Problems:
The chassis looks pretty rough with several rust spots which may (or may not) have been made by Mickey and Minnie.
The dial cord is broken and the pointer is MIA. I'm pretty sure I have a pointer, though.
The dial lamp holders (upper and lower) for the left dial lamp are missing. I'm hoping I have suitable replacements in my parts stash.
I had previously removed the FM limiter coil and ratio detector transformer. I started to use the ratio detector transformer in my 100-T Coronet tuner/preamp last Christmas, but as it turned out it would not work with that transformer so I ended up reinstalling the original. I think I used the limiter coil and ratio detector in another project (an FM-100-C which I restored and later sold).
At the same time I removed those coils, I also removed the WX multiplex decoder for another project which never happened so it will get reinstalled in this chassis once it has been recapped.
I had already installed the FM limiter coil (but had not yet wired it in) when I took the photos above. I then installed the ratio detector transformer and wired both back in as they should be. This limiter coil and ratio detector transformer came from a Fisher Ambassador V tuner (680-T chassis). Comparing these to the coils in my good FM-50-B, the part numbers of each are the same as those used in the FM-50-B so we're good there.
Next job: to install a terminal strip and four diodes to replace the original selenium rectifier, along with a 100 ohm dropping resistor in series with the B+ output.
