Plug cleaning

My uncle had a service station in the late ‘50’s into the ‘60’s and he had one of these. I would spend hours there cleaning spark plugs. I also spent time jacking up his hydraulic jack then climbing on it and making it go down Like riding an elevator. My dream job was to work there so day but my uncle closed the business and worked as a mechanic for the power company. My dad asked my uncle to put a clutch put in his Chevy pickup and my uncle told him that I was capable of doing the job. I was just over 100 pounds at the time and had to use my feet while folding the tailshaft go get the transmission to go back into the bellhousing.
