unique and unusual early 1920's vintage american industrial mobile factory cart and machine base, salvaged from a chicago-based radio cabinet assembly plant. the portable cart originally contained an electrified device with toggle switch mounted along the front side. the uniquely-shaped four-sided base is comprised largely of pressed and folded steel supporting multiple wood plank tiers or shelves. the "bassick" swivel casters remain in excellent working condition. original green paint finish remains mostly intact. measures 21 x 30 x 36 inches. fabricator unknown.
