There's not too much. I live in Lebanon, OR, where P&C was once based, and I'd love to determine where they were. I'm sure the original building is long since gone (there's not too much from that era still around), but it sure would be cool to dig up some more information.
I'm going to have to hit up the local historical society - would be neat to get an print of an old picture for my shop wall. Still trying to find a picture of my grandfather's Richfield station to do the same thing...
