Cool looking little ride! I hadn't seen this style in a looong time.
As kids, (always broke but dreaming) cousin and I used to drool over them, the Powell
P-81's and, of course, the Mustangs. The shop owner would ignore us for a few minutes and then run us out.
About '64 I bought my little brother a used Simplex scooter - more in the Doodlebug style - with a busted engine. (Cousin had a Doodlebug around '49.)
It had a Continental go-cart raceing engine. 'Needed a Rod and piston - both alloy (no crank damage). Finally found parts and gaskets in Atlanta.
The little rascal was "geared" low and turned lots of RPM. The little engine would really wind! It would sling gravel and hit about 40 mph in a flash - even with an adult on it. Cute, fun little scooter! 'Can't recall whatever went with it.
