[Splash]

Hello
Found this piece of armored steel with a small bunch of Humvee parts that came into my hands. Anyone know what it is?

No part numbers, but looks like its off some kind of vehicle.
35 1/2" long 10 1/2" wide 4 1/2" thick with out the handle. made of 3/8 steel and is 40 lbs.
Paint on all edges so it is not cut or anything, the weird shape is it shape.
Thanks

It's off an airplane!

A good friend once said, if it's not on and airplane then it's off an airplane.

Can't argue with that...

Most parts have a number some place stamped on the part. You might have to look hard, but it should be there. If you can find it, we should be able to tell you something.

Actually, there should be two numbers. One will be five digest, the part manufacture/suppler, (FSCM code). The other can be anywhere from 4 to 20 digits and or letters, dashes, slashes and hyphens.

I have gone over every inch (CSI style with mini mag lightheld up over my shoulder and everything) and can’t find a hint of a stamp or depressionin the paint to look under. I am stumped but I hate throwing things out.
