Vintage pair of industrial stools

Vintage pair of singer style sewing stools. Likely produced in our around the 1930s. The stools are a lookalike for certain singer stools, however these are not marked as some are. These also do not have the ability to be adjusted in height, it looks like this was never possible. The stools are cast iron, and the top is made of solid elm. The tops look to be a later addition, but they look very genuine. The pair is in good, patinated condition. They are sturdy, and we have cleaned and waxed them.
