Now if the P-15 only came with 27's I'm more inclinded to believe it was designed for them, especially if it was a touring model.
P-13: Road Racing Paramount. Frames could be anything from the genuine road racing model made for 700Cs (usually tubies) only, or a model made specifically for the larger 27" rims; essentially a P-15 with an NR rear derailer and double chainring, as opposed to the P-15's triple and long cage RD. Eyelets optional on all variants.
P-15: Touring Paramount - made specifically for 27"s, and outfitted with an NR double and long-cage RD (either Valentino or Shimano). Eyeleted dropouts.
P-10: Schwinn's new model number developed in 1973 for the 27"/double-chainring variants of the P-13 as explained before.
If you're still confused, I woudn't worry much about it. At times, I wonder if the factory knew what they were doing themselves.
