Mystery Body in Spencer

Here's our latest mystery car. Matthew Gustafson recently snapped the above photo of a car body - or what's left of it - in the "back 40" at the North Carolina Transportation Museum in Spencer, NC. I haven't been able to find any information at all about the car. It appears to be, or have been, a single-truck arch-roof car with doors at all four corners and six windows per side. To my eye it has a bit of a Southern Car Company or Perley-Thomas look to it but it's hard to say. If the car is from a relatively local system that would make sense, as those two companies were located nearby in High Point. And Southern did build similar single-truck cars for Southern Public Utilities, which ran the system in nearby Salisbury for a time (a photo here of one of the SPU cars even shows that odd single-bar window guard like the Spencer body has).

Then of course there's the question "is this thing actually preserved?" As poor as its condition is, I have a policy of putting any electric car owned by a railway museum on the list, even if it's not currently accessioned and even if it seems forgotten. You never know when priorities may shift and that cadaver out back might go into the shop for a paint job. And, you know, a roof. But if I haven't the first clue what the identity of the car is then I don't have enough to add it to the list. You can help!

UPDATE: Thanks to Wesley Paulson and Dave Lathrop, who have provided information indicating that this car came to NCTM many years ago after a period of storage at the Salisbury depot. Local legend has it that the car did indeed run in Salisbury but there doesn't seem to be much documentation of that, as photos of Salisbury cars mainly show Birneys and double-truck cars. Anyone have any photos from Salisbury that might show these pre-Birney arch-roof single-truckers in use there?
