Original Aeronca Drawings indicate the data plate was on the baggage compartment sidewall. If anyone is interested the San Diego Air and Space Museum at Gillespie Field is restoring 43-27165. Stop by and visit.
On the wing root of the TBMs there are 1/4 inch diameter rivets. They are very difficult to rivet. If you visit the WWII Museum in New Orleans you will see my work. That plane was a fire bomber and we brought it back to display quality.
And some more.. oops. the last images are of a high altitude intercept and then some concepts when he went to Argentina. A number of years before the F-86 and MIG-15.
