There’s many mid 70’s Fenders without the stamps, so I wouldn’t worry. From the pictures there’s nothing that stands out as suspicious. Would be nice to the see the pickups and under the guard though, just in case.
Because of the bolt on neck, some old Fenders can become Partscasters, but for me it’s not a worry on a refinished bass like this because the parts look right for the age, given the pics available.
