Hi Stephen,
You want to look at the schematics and service data for the Model 112 above serial number 174001 (which is the 2-47 version). I don't have access to any of my stuff as I'm at work on lunch, but I believe the data on Rider's Philco page 2-38 is correct for your set. Almost everything above that is for the early 112 with 2-45 tubes, below S/N 174001 - the exception being, as you mentioned, the under-chassis drawing at the bottom of Philco page 2-36.
It's hard to make out in the scan, but you're right - the numbering scheme of the terminals are different in the 2-36 drawing than the 2-38 drawing. However, I am pretty sure that the capacitor layout in 2-38 is correct.
I will look at my notes when I get home to confirm, and to be able to properly answer your questions.
