I just learned that this aircraft was erroneously identified by numerous sites on the web. Since 1612 was undergoing restoration in 2005, with photos showing the extent of the damage from being on the bottom of Lake Michigan, the aircraft in this profile could not have been 1612. That's what I get for trusting the 'net for ID without double checking!
This aircraft is really an SBD-3 (vs SBD-1), BuNo 06583, with c/n 1320. Engine should be Wright R-1820-52. Although it was at Battleship Alabama when I took these photos, the current whereabouts is unknown. It was damaged by Hurricane Katrina so it may be under restoration somewhere.
Can this profile be edited with the above information so as to change ID and engine? Or should a new profile be built and this profile deleted?
