Professor Anthony Barker's Strength Maker Kettlebell

Kettlebells? They have a longer history in America than you might think... Case in point,  this "Strength Maker" kettlebell, was produced by Professor Anthony Barker around 1910 or so.  The "Strength Maker" was a set which consister of two hollow globes and various handles.  Depending on what you wanted to train with, you could screw in a short handle to make a dumbbell, a long handle to  make a barbell, or the handle shown above to make a nifty pair of kettlebells.  The globes were hollow and weight could be adjusted with shot as needed .
