Russ:
I can remember seeing one way back when, but never used one. Sounds like it "might" have been a cow barn pa mike used to call the cows down in saragosa.
Got a scooter story for you. Its about my 1942 cushman(airframe). When I was 12 years old, my older brother bought it for me for 25 bucks in Martinez, Ca. He took the chain off and stuck the front wheel into the trunk of a humpback (37?) Chevy and brought it back home to Ariz. Well the rear tire wore off all the tread from the 800 miles of being dragged, and I needed a tire. My Dad had just bought a new const. wheelbarrow That had a road tire on it, after much pleading and jumping up and down, I convinced him that a wheelbarrow was'nt going that far, and the tire would probably outlast him. I traded, and pretty well wore out the new tire before the scooter got traded off for a Model A. MY dad passed away in 1969 and I inherited the wheel barrow. I used it in construction for years, never had to put air in the tire (not once). When my wife's dad passed away in 1987, cleaning out his tool shed I found a brand new tire in a box. So decided that it was fitting to give the barrow a new tire.
When I undertook the task of changing it, I got a suprise, there was no air in the tire, the rubber had turned to stone, and had to hacksaw off the old tire. The tire did'nt look any different than it did originally except for some cement stains. SOO, when it comes to Cushmans, even the tires were built to last forever. I figure about 45 years for that tire, and I've been sorry ever since that I cut its life short....
