I doubt this magnified insignia from below the pilot is not much help due to poor image quality but posting just in case it jogs someone's memory. Thanks to all responders.
This is one I'd love to see a set to convert from the Accurate Miniatures (and its clones) 1/48 kit. The closest thing I've been able to find is the Belchers Bits conversion:
Actually, I should probably just get this set and be happy with it, it would be "close enough", I think. Other than me (and the lovely Mrs), no one sees my models anyway…
I'm thinking I'd love to do one in this scheme (strikes me as ironic how the Japanese used an aircraft postwar, that was of such significance in their defeat during WW-2). I also think the Light Gull Gray and White scheme looks really cool on the Avenger. A TBM-3W conversion would be nice, too.
My friend found the pilot's scrapbook with a 1950 Saturday Evening Post article on the Avenger sub hunter mission and pilots flying from the USS Mindoro. The pilot we are researching is seated on the far left in the briefing room.
Aircraft History Card for US Navy TBS BuNo 91512 Has been received and I'm attaching for anyone interested. Thanks again for all the responses and expertise.
