My champion from 1978 looks a lot like this. Link for picture only. It also came with a grain mill and bag that I never used. The big round part laying on its side is the motor. I swear it’s a water pump motor.

That’s a serious juicer.
As much canning as I do I should probably bite the bullet and buy a commercial unit similar to that one.
But for now I’ll use the Ninja juicer until I decide I hate it or until the smoke comes out.
