"That orange drop and those round disc capacitors definately arent OEM. "

That "orange drop" is likely no less original than that round disk capacitor. By that I mean that disc capacitors ( AKA ceramics ) and paper/foil caps coated in opaque orange wax [?] were not unheard of in radios of that vintage, ( admittedly caps coated in transparent yellow wax were much more common in that era ).

Interestingly that orange coating on the very old caps tended to be very much more brittle than the yellow wax coating. I can't honestly say whether the coating on those orange caps was simply a brittle type of wax or perhaps some early sort of thermoplastic.

I can't say when ceramic caps were first used but can say that as a kid butchering old radios in the early to late 50's I saw them often enough so as not to take any particular notice.....Unfortunately I then was literally nothing more than an enthusiastic but utterly uneducated/unintended vandal for the most part and often cringe now about all the very early Atwater-Kents etc. that I destroyed while attempting to become the next DeForest or Marconi

If I had known then what I know now I wouldn't be schlepping back and forth to my city job every day. On the other hand I may still wind up getting my 15 minutes for being the oldest computer tech in Calgary to drop dead on the job.
