I received the AAF aircraft record card the other day. The Tallmantz A-24B,
42-54682, was accepted by the Army on 11/8/1943 and was immediately earmarked to go to Mexico. It was flown to the San Antonio Air Depot where, the card notes, Mexican pilots would pick up the airframe. This pretty much confirms that
42-54682 was one of the 30 A-24Bs transferred to the Mexican Air Force, though its serial does not appear on the only tie-up listing I could find (in
Douglas SBD Dauntless by Robert Peczkowksi) showing the Mexican A-24Bs.
Another peculiarity is the record card shows the airplane manufactured by Douglas at Santa Monica, but this is clearly incorrect as no primary or secondary sources show any A-24Bs built at Santa Monica...they were built at Tulsa. Perhaps the airplane was actually 'delivered' at Santa Monica but that really makes no sense. It's hard to understand how a basic reference would be incorrect...the whole batch of A-24B cards were presumably prepared at the same time and they show the wrong manufacturing plant? Mysterious.
In any event, I updated the page at my Tallmantz site:
https://www.aerovintage.com/the-tallmantz-a-24b/. A copy of the card is on that page.
