A tall order. ID this WW2 aircraft wreckage from a mangled mess

[P-59A]

Normally this would be easy peesy, but this is from Chino Air Field. After the war they scrapped many aircraft there. Several years ago they broke ground for some new  hangers across from the Planes of Fame and they exposed a dump and burn pit from WW2. I kid you not it was tons of metal they exposed. After everyone at the airfield picked through it I snuck in and pulled my own little keep sakes. This was one of them. I have no idea what it is from so I will go one or two pictures at a time. This is the over view top and bottom. That dark grey paint is either early WW2 Army or Navy. This looks to be the bottom of a wing.

In this photo you can see a part of the National Colors. This leads me to believe this is the bottom of a wing.

This stamp says 5060510-12. The only WW2 aircraft I have with a prefix like that is the SBD. One of its numbers is 506-----

In side the folded metal I see this number. The style is WW2. Maybe that first rivet covers a number, but as it reads I can't find that number.

Also in the folded metal is this in pencil.

On the inspection plate is this ink stamp. The only way I can see to ID this is to line up the rivet pattern to the underside of a wing in the area of the National Colors. I do not have photo's of the underside of a SBD. That grey could be a USN grey, but I am not sure. Also the two coats of zinc chromate may be a Navy thing. I can not recall seeing two different coats on USAAF aircraft crash sites I have been too. I have only been to one SBD crash site.

The rivet pattern and the type inspection panels are in keeping with the SBD.

This is a bottom wing section of a SBD. The section I have is in the yellow. The rivet lay out lines up and its the area the National color is located on the other side.

I can't help you with your questions but pulling that stuff from a garbage pit is really cool, thanks for sharing.
