I bought a J3 c-65 Piper Cub with a Flottorp propeller.
The serial number is A25811E
Model number: 72 A 48
Can anyone tell me the precise date of manufacture ?
* It also has 1/8 " laminations
(To tell the truth, I'd never before heard of a Flottorp, but the company evidently made a bunch of them! I'll report back what I find.)
