I photographed these Piper J-3 examples at several events and museums. During WWII, the Army The Army purchased 5,677 Cubs as L-4 Grasshopper to help fill the observation/liaison role.
Piper J3 Cub 40-0003
The museum registers this as a Piper J3 Cub but also has a military-issued number for the airframe
