I haven't found the side number but according to Joe Baugher's site ( http://www.joebaugher.com/navy_serials/navyserials.html ) this is the fate of the aircraft:
74037 (VC-81) attached to Natoma Bay (CVE-62) lost off Bonin Is in central Pacific Mar 3, 1945.
And the squadron log has this information for 3 March 1945:
The 16th day at Iwo Jima, 3 Mar. 1945, was eventful. It opened with a strike on a reported concentration of large enemy transports at Chichi Jima. Eight FM-2' s from this squadron participated in the attack. They made three attacks; on the first firing rockets at the shipping and on the second and third attacking AA positions to protect the torpedo bombers which were following. The shipping was identified as one medium transport vessel and small FTC class freighters. Damage was observed. On the first attack as the fighters were retiring toward the entrance to Futami Harbor, The FM-2 piloted by Lt.(jg) Huston was apparently hit by AA fire. The plane went into a 45° dive and crashed into the water just inside the harbor. It exploded on impact and there was no survivor or wreckage afloat. He was one of the squadron's better pilots. He was quiet and unassuming, always alert and his keen eyes tally-hoed everything within sight. He was always the first to sight aircraft and shipping; he tally-hoed the only submarine sighted by the squadron. He was credited with the destruction of four airborne enemy aircraft.
The same day, on the 1000 launch, Lt.(jg) Tate's FM-2 veered to port due to a heavy roll of the ship and despite prompt and correct measures taken by him, it went over the after stack and into the water. He promptly disengaged himself and was picked up five minutes later by a DD with no injuries except· minor bruises.
So, 74037 could be Lt(jg) Huston's aircraft or Lt(jg) Tate's...both lost on 3 March but I can't find who was in what aircraft. Chichi Jima is part of chain of islands known as the Bonin Islands.
If you can find the official after action reports on these incidents, they should provide further information on the specific aircraft, BuNo, and side numbers specifically.
On further investigation...I came across some interesting information regarding Lt(jg) Huston, apparently back in 2005 some parents claimed their kid was Lt(jg) Huston...reincarnated:
Is his the aircraft you're looking to build by chance?
