In fact, York Barbell was still producing globes like this one until well into the 1970’s. Unfortunately there are no true solid globe dumbbells currently being manufactured today, so if you see any, better grab them quickly because they are exceedingly rare.
For the better part of the last century and a half, globe dumbbells and barbells were the “art form” of the Oldtime Strongman. Many were hollow, which allowed it to be filled progressively with shot to increase the weight and produce a unique training effect. Others, like this one, were solid, and just fun to train with. Several companies used to manufacture globe dumbbells: The Good Barbell Company, The Jackson Barbell Company and, of course, The York Barbell Company who made this one.
