|I bought this Medai "Top Super Floor Pump" about 1974 or 75. These were one of the best pumps around at the time. They had a reservoir can with a pressure gage on top with readings to 140 PSI and 10 BAR. I pumped up a car tire with it once, a lot of work. They originally only had a Schraeder valve connector with a thumb lock but later ones came with a brass adapter for presta valves. The hot ticket was to get a large brass Silca presta air chuck and use it with this pump. Schwinn private labeled these pumps.
