Ohio Vending Machine Co., Columbus, OH, c. 1930, 14" (left) and 14 1/2" (right). These are kissing cousins of Columbus, and for all I know they're Columbus in disguise. Columbus, Simpson, Ad-Lee, Ohio Vending Machine Co., and probably some others I can't think of right now seemed to be a pretty incestuous bunch. I think this was a separate company from Columbus, but I'd bet there's a close relationship there somewhere.
Pictured above are 2 versions of the Ohio Vendor:
Most don't have decals; the one pictured above left has half an original decal, with the bottom half now missing. All of the aluminum versions I've seen have had the "vertical bar" gate shown on the machine above.
