From a '67 GS400 I parted out. Says Delco on the lid. It has bleeders above each outlet port. Casting number on the bottom of the master cylinder is 5460465. Is this the master cylinder that came with the car when new?
I think it is, but I'd have to check more to be sure. The casting number and part numbers are usually different. On the machined pad at the front There should be 2 letters stamped. The cap looks original, too.
