I have a piece of ordnance marked 90MM M11 AA1 . Dated 1977. NOR 06-005. It was in my dads yard for years and I just don't know enough about this stuff to know if it is safe or not. The casing is steel and there used to be a pointy piece of aluminum over the chunk of iron that is the projectile but it corroded off. I have not seen a primer system like this before. the center hole almost looks like a bolt and the off center hole looks like it has some sort of resin in it. Thanks for any help you can give me to know if I should call the law or if it is safe.

its inert...looks like a screw in one hole. there would only be one primer, similar too this. 

Thank you. That's what I thought but it's good to hear from someone who knows for sure. Dang thing must be full of rocks though.

What are the "studs" on the 90mm projectile?

They were holding on a piece of aluminum that was conical and came to a very sharp point. but it corroded away over the years. made it look a lot more streamlined. it only covered the top portion of the projectile where the rust is.

OK, so am AP-T M318. Did not know these studs were under the wind shield.

 

 

90mm APC, solid bolt. It does not have its windshield, no explosive charges, A good boat anchor.
