Also of note is the dumbbell pictured in the ad… Various types of Milo Barbell equipment, dumbbells, barbells, kettlebells etc are quite rare these days but they do turn up on occasion. Only one of these particular shot-loaded dumbbells is currently known to exist, however. The lifter of said dumbbell in this ad is Mr. Frank F. Jones, weightlifting champion of Philadelphia. As noted in the ad, Mr. Jones’ bodyweight at the time was 140 lbs. yet he could lift this dumbbell loaded to 150 lbs. with ease.
