Can anyone identify this hood???

Hello, wonder if any one can give me some info. about this hood, i bought it in a lot of speed equip. Im told its an early 70s cuda hood made for or by a race team.. can you prove this right or wrong???
-Very high quality matte black fiberglass, looks factory made
-has hinges on back, pins on front
-has part # sw 30-1 (I think, its stamped backwards & hard to read)

Ive tried to research for pics but the closest ive come is a challenger TA, which is close but not it. Im not real good with my mopars yet, so any help would be really appreciated.... see pics.... Thank You!!!!
