1) It plays, but crackles.
Check any remaining capacitors that have not been replaced. Test the tubes.
2) Somebody replaced capacitors, so I mainly need to check that work, and finish replacing the electrolytics and a few otehrs.
There is one bakelite block under the upper chassis. Do not disturb that bakelite block! That does not contain a capacitor, but instead, it contains the coils of the 10 kc audio filter.
2) I see no sign of cleaning

3) The various rubber parts (tuner mount, etc.) were not replaced.
Contact Ed (Blacksmith) for these:

4) The cabinet will need to be refinished.
I can't help you here, others will hopefully chime in.
5) The original dial lights were discarded, rather than rebult, so I will need them.
You can get these from any of the 1937-38 Philcos with the Automatic Tuning mechanism. It should not be too difficult to find these.
6) One tweeter cone is all broken-up, so I'll have it re-coned.

7) There is some strange added antenna wire, but connecting to the "red" terminal also works. I was able to receive a few stations on AM and on shortwave with a 10' piece of hookup wire.
On 1938 Philco models, the "red" terminal is the antenna terminal. I can't address the added antenna wire without knowing where it connects inside the chassis.
8 ) There is a strange two-conductor shielded cable with the two conductors connected and covered by old friction tape.
Is this connected to anything inside the radio chassis?
