I live in a 1920’s vintage apartment in the Marina. It has two interior “closet” doors that open into teh living room from a small interior room. The doors are not equal in size and one has a heavy 1" diameter vertical pipe that acts as a hinge/pivot. The 1" vertical pole has some old mounting hardware near the base coated with several layers of paint. My impression is that this was once a pivot mount, fold down, 1920’s equivalent of a Murphy Bed. I would really like to re-install this hidden away bed but I can’t find any images or hardware after multiple google searches. Anyone ever seen one of these or have knowledge of vintage hardware or plans?
