A while ago I modified the three gang condenser drawing, I drew it wrong

Well, Now I have something to understand this radio.
I found a few schematics with the same tube line-up (77 as detector) in "Rider's perpetual" thanks to the searcher of www.americanradiohistory.com.
Very strange line-up indeed, there are many more schemes with 75.

Not the same but very close:
Electric & Automotive Prod. Co. mod IL-55-LW and mod. IL-5.

Same line-up, they are similar but they have two gang capacitors:
