Yes looks to be a white marine pearl set. If those stands are original to the set then it's a "Hollywood" set. Big Beat was exactly the same drums with heavier Atlas hardware.
Serial numbers would be on the lower panel of the badges but there were a couple of periods in the early 70's where the badges were missing the serial numbers. The serial numbers can give you a ballpark idea of when the drums were built but otherwise do not contain any sort of coded information.
If you look inside the drums there may be small ink stamps of the production date inside one or more of the drums if they date from the early 70s. These stamps weren't universally applied though and were easy to wipe away if someone cleaned the inside of the shells. The stamping was discontinued fairly early in the decade.
Looks like a very nice set. It's possible it could be older than 1974 as sometimes drums could sit in a music store's inventory for quite a while. They do look to fit that general time frame.
