75mm AP-T shell: What fired it?

[RustyRelics]

Yesterday I walked into a local gunshop, and found three super rare and expensive German WWII marked Sturmgewehr magazines, and this artillery shell. I bought the magazines for $20 each, and got the shell for free.

It is solid metal and inert. The "fuse" in the bottom is where tracer compound would have been placed. It measures 75mm diameter, and is 8 3/4 inches long. I believe it is a WWII Anti Tank round for a Anti Tank gun, or tank round, but I'm not sure. It's Armor Piercing whatever it is. Any ideas what fired it?

Sherman tank maybe? Wikipedia says the tanks gun had a 75mm gun.

It might be a 76mm or "3 inch gun" if Navy practice "dummy" projectile missing the rotating band.

And pretty close to one in this image, 4th in from the left, from a French WWI 75mm (used by all Allies in WWI).

Sherman was my thought as well, but doubtful as all Sherman shells have a different base.
