The Airforce museum has made an error in the caption of the photograph.
It is a Grumman OA-12 (J2F Duck). The Air Force museum have made errors before, and I have e-mailed them to correct their mistakes.
There is just no way the photo on thread #325 is a Cessna 195 (LC-126).
Here is the USAF museum's Grumman OA-12. Note the fenestration.
