I can fill in a few details.........
First, this PCC Car started its life in Cincinnati circa 1947; which sold it to the Toronto Transit Commission, or TTC, as an operating vehicle, along w/the much/all of the rest of their fleet in 1950
The TTC then got several decades of life out of it, before giving it a major rebuild in 1987, and actually changing over to modern livery.

The TTC would later repaint it in its classic colour scheme.
TTC retired the last of these from active service in December of 1995.
From there, it appears to have been sold to the Michigan Transit Museum, in 1996.
