There are lots of pics of 1974 4001 basses in the register.

The TRC in 74 was clear plexi with a stenciled Rickenbacker logo
Big question is was this bass White Trim or Black Trim?
The back of the Black pickguard has no pieces of white masking tape between the pots and the plastic...This suggests to me that the black pickguard was added after it left the factory. This is not definitive but it does perhaps suggest it was added later. Perhaps when the black finish was added. Black on black is a cool combination.
MG basses were more commonly White Trim in this era... Yes there are examples in Black trim but they are rarer.

White basses were almost always black trim... But then the binding would be back too if it was a white BT bass before it was stripped to maple
I would say that your bass was more likely to be White Trim as well by the white binding on the neck...
Good luck with restoring it back to original - sounds like a great project!
