Gibson 1936 Super 400
This Super 400 has a little history behind it and looks to have been exported to Canada. According to Lynn Wheelwright,
'Caldwell & Co. MC might have been owned by Wallace Caldwell or a relative. The MC stands for Manufacturing Company, a lot of jobbers used this although they did not manufacture anything. W.H. Hauling is an exporter to Canada.' Which explains why this piece has a 'Made In USA' stamped on the back of the peghead.
