July 20, 1959 Doug Hepburn pressed (no clean) 440 lbs from the shoulders. This was two years after Anderson's Mapes stint, so Doug had the strength to get 400 overhead, so perhaps he would have been able to get the 400 lb globe bell overhead at Mapes so he could qualify for the Silver Dollar squat?
