1931 Airline 62-141- Need Advice

[Winky Dink]

I've had this on the bench for five months. Recently got a legible schematic (Did you know that Rider's has an early edition of Volume II? The schematic in the later edition for this model is terrible.) I'm ready to rebuild the paper caps, but I'm puzzled about modifications not shown on the schematic. Please understand that I'm still trying to learn "radio stuff," so if I misspeak it's because I don't know any better, and corrections are welcome.

I have good photos and diagrams in a Picasaweb album.

In the modified schematic (direct link below) I moved components to give me a better visual picture and added arbitrary component and terminal labels to correspond to my photos.
Modified schematic:

Three questions:
Does my markup of the modified schematic make sense?
Should I restore by the original schematic or try to duplicate the modifications I see?
Who were they making 25-cycle radios for?

Thanks for your help.
