Hi and Welcome to the Phorum,
Here's plan B.
We know the set was made in 1955. So we look around other sets that using the same tubes and topography to find something you can use as a guide. Here's a good place to start https://worldradiohistory.com/Beitman-Manual.htm I took a quick scan @ 1955 and a few sets in the RCA and Zenith section that maybe helpful.
Don't get too hung up on the selenium rectifier it's just a resistor & diode vs a tube. Doesn't amount to a hill of beans circuit wise. Move around a bit with the years. I was surprised to see that most of the set listed in '55 AM radios, tube portables, and phonos.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
