WWII US Coast Guard J2F Observation Aircraft Fabric 1937 WW2 Airplane

Description

I’ve got several other sections of this fabric. All seem to have some sort of damage or patching done to them. Tears, missing paint, etc. These come from a family estate of a military collector who also restored aircraft many years ago. For additional questions, I can ask the family and they may or may not have additional information. Thanks and happy bidding. Just testing the waters to see if there’s any interest in this stuff.
Dimensions approximately 18” x 26”
I’m told this aircraft was wrecked and this wing fabric removed from the aircraft and replaced.
