I found this behind the 1941 Mabel school building in Mabel NC (Watauga County). I am no expert, but I think this is a late 1930s or early 1940s
General Motors International unit. It was modded by Buffalo Appliance Company. The badge and any identifying marks are gone. I couldn’t get inside because a bee colony had taken up residence and they were buzzing around acting annoyed. I did manage to take a picture of the interior, though. If you have better data on this, please let me know.
