'32 V8 badge, Rad. cap & '34 hood parts. Junk?

[tomcarman]

These were identified by a respected fellow Barner but I don't know if they're junk. '32 V8 badge. Pitting and a magnet won't stick to it. Junk? '32 Radiator cap in decent shape. Has been hanging on the wall for decades. Magnet sticks to it, no visible numbers. Has a bit of heft to it as if it were built substantially. OEM? '34 hood badging I know is junk. Made in Argentenia, magnet won't stick to it, has a chip out of it. Wall hangers?
Thanks,
Tom
