U.S. 75mm APCBC projectile

Trying to ID if the (M61?) 75mm Armor Piercing, Capped, Ballistic Capped projectile in the photo has a base fuze or merely a plug. Or, is this the APC M62 ot the M72 AP (shot) projectile? No markings.
Thanks!

This is the 3" (or 76mm depending on when made) M72 or M72A1 APC. It’s plugged, not fuzed. The M66A1 BD Fuze, used with the live loaded projectile, has a protruding base containing a tracer.
