In all the Rider's schematics I've seen, (which is what Nostalgia Air uses), you can count the pins easily on the diagram: Start with the filament pin on the left (looking at the diagram), this is pin 1. Each pin in turn is 2, 3, 4, etc., with grid caps shown separately with a [ on the side of the tube.

If you want really good service literature, Philco Repair Bench http://www.philcorepairbench.com/schematics.htm is the place to go for complete literature. Steve Johnson also has some very nice schematic packets available for download http://www.antiqueradioschematics.org/philco.htm
