I bought one in 1984 and have used it dailyweekly since. I've replaced the hose but didn't like the hose clamp and so whipped it with heavy thread. It's only had the brass presta chuck and I've replaced the rubber gasket many times. I've swapped out the leather 731 gasket probably once every ten years. Maybe I should look for a new gauge as after 30 years of being pressured I think it reads high. Or just plug it off, and use a hand gauge.
If you want a bike tool that's worth more than your bike, and would rather have your bike stolen than lose this pump, you know what I recommend. I like the simple rebuildability.
Watch the shaft diameter, when they sent manufacturing to Asia they reduced shaft diameter (like the Super Pista thumbs down)
