Antique Factory Cart Cast Iron Vintage Wheels Railroad Dolly Industrial. Nice set of antique wheels, overall in great shape, very nice original items. They do have a set screw in each so likely began life as a different wheel or pulley but a nice matching set. set screws are free. With the spokes being a little bit finer roughly 1 wide and 3/8 thick wouldn’t be great for a ton of weight but a great looking wheel Wheels measure a hair over 15 1/4 in diameter. Hole in the center is a hair over 3/4 I would say just shy of 11/16 Tread is about 2 1/16 wide They do weigh a bit over 13 1/2 pounds apiece
