F7 Tigercat is my 'guess' too. Have never read if any were actually used in combat. I recall Grumman built them too late to be deployed in WWII.
They were used in Korea. Also saw service as fire bombers her in the US. It's not really apparent in the photos, but the fuselage is so narrow it is almost odd to view them head on. Less than 36" is my guess.
Here's some pics where you can see how narrow the fuselage is on the F7.
