I do have those ID's, thanks Almar
You're right, they are they same part from the AMT/MPC Slave I Display Stand.
Now, the part behind the Slave I stand is one that I have not ID'd yet. It is a little bigger than the Slave I part, and looks like it has two spru tabs still on it...? I suspect it to be from an aircraft, like the Pylon or a wing flap...
I can go cross-eyed staring at these pics. I traced over the parts again, this time using different colors to represent what I think are different parts to try to help get a better idea what the part shape is.
The Blue parts, I first thought, was an L-shape with holes in it, but closer look, I think the dark part is shadow from 'fins' (triangles) on the side.
The green 'butterfly' wings look like they may have dimples around the curve. I first suspected a wheel fender, or the opening for aircraft landing gear, and even thought that it could be from a hull of a battleship...
The purple parts def look like wheel fenders, either from a car (have not Found any F1's to have this kind of wheel cover) or something like the 20mm Flak
The orange parts def look like Pylons or or similar aircraft part
Any thoughts?
