Help with ID, possible 90mm WWII AP Anti-Tank Shell

[Rod266]

This shell was found in the desert near Barstow CA in 1982 when a guy drove over it in his motorcycle and was tossed into some sagebrush.

I may be a US 90mm armor piercing anti-tank round; there is a threaded shallow hole in the base for possible tracer placement.

Am I on target with the ID?

Looks like it might be one of the highly coveted GOLD M77s.

Definitely looks like a 90mm AP SHOT Tracer projo, minus rotating band and tracer element.

Thanks for your help.

for 90 mm M77 US, rotating band must be 30 mm of large
