It is most part there and has seen heavy use the bakelite blocks where bypassed with just caps hanging in mid air and modern carbon comp in places. I had to repair the volume control it was half apart and hanging but after cleaning and assembly it tests fine. 
Some of the values where not correct i am guessing a WW2 repair? All the coils and transformer test good. 
Here are some pics i even found a repairman's tag.

Yes paralleling newer caps to backelite blocks as they failed was a popular albeit ill-conceived measure.
Yes this would restore capacitance, but wouldn't remedy the leakage.
