On an old map, Perryville was also called Toboxy (I assume not the original town that was burned but the water stop of the post-war railroad). It appears in Grant Foreman's list of post offices that Buckluxy is the same as or is nearby Scalesville. In the book "Ghost Towns of Oklahoma" is a reference that says Scalesville was a store, blacksmith, and a couple of residences. Not much of a town but a known landmark.
I think the Indian-Pioneer Papers (WPA Federal Writers Project) may be a good source for more info. Anyone frequent the library at NSU-Tahlequah or OHS in OKC?
