I'm sure Funk has pictures of this movement, the one arm bent press. Which was a key strongman lift way, way back in the day. The old globe (some loaded with shot) type BB , before the modern revolving type Olympic plate bar, made the exercise extra hard. Some used old style kettle bells. Seen a picture of a man using a anvil, and one a motor block from a car.
Europe, with it's long history of strongmen, made the bent press one of it's standard lifts, with regular contest. The great Sandow (if memory serves) used over 300 as part of his strongman act (not sure if these stage weights were less than claimed...might have been) and he was around 180-190lbs.
Rather than one handed cleaning the bar to shoulder position, some stood the bar on it's end, squatted down and rocked the bar unto their shoulder. Kind of impossible to one hand clean a heavier bar. A few would two hand clean the bar and slide it into position on the shoulder.Their lockout power was something else.
Another old timers lift that no one sees anymore is the two hand Continental lift (aka..the two hand anyhow). Just brute strength and a little technique was applied to hoist some very impressive weight over head. Could take 20 to 30 seconds to complete one rep. can be kind of painful to watch, ut still impressive.
Both of these lifts were from a era of true strong men. No drugs or chemical engineering, just lots of beer, for many of the lifting contest were held in , and around, beer halls in Germany, France, Lowland country's, et, etc, etc..
