ALTO interlocking diagram

Hello Everyone-

I'm looking for a scan of the interlocking that ALTO tower controlled. It can be any era, PRR, PC, CR... Going to used as an illustration in an upcoming magazine article. I looked in all the usual places and couldn't find anything... Any help is appreciated, email me directly please.

The question deserves a public answer. There are many PRR interlocking diagrams missing from the "usual places" and I've never found this one posted anywhere.
But if you inspect the pictures at the following link you can draw your own diagram. What a hodge-podge it was!
