I emailed Harvey Eckert, who corresponded with Don Schumacker (who many of us know to be the Curator of the Mack Museum and the Archivist) some time ago, and kept the response, which Harvey was kind enough to send back to me:
Don writes: "The Mack Bulldog ornament was patented in October 1932. It was released as Part Number 4BF26. In December 1937, it was redrawn and the part number changed to 27RU217. This was a chrome-plated zinc die casting. It did not change until December 1941 when the finish was changed to a painted #775R Mack Gray finish. In September 1944, the finish reverted back to chrome-plating.
In September 1947, the part number was raised to 217RU217A; the attaching studs were changed to cast-in female thread brass fasteners. The P1 version was chrome-plated. In June 1967, the 14 karat gold-plated P2 was released. In June 1968, the gold plating was replaced with 14 karat gold alloy.
In December 1979, the ornament was redesigned to incorporate shorter ears and tail to make it more friendly when using it as the handle to tip the conventional models’ hoods. The part number was raised to 217RU217B and the patent number was changed from 87931 to 1,387,477. The P1 part was again chrome plated while the P2 finish was “gold flash.”
Starting in 1966/1967, the original “gold” ornaments signified that a vehicle featured the Mack Maxidyne engine and Maxitorque transmission. All other Mack trucks used the chrome plated ornaments. Starting with the introduction of the CL Model in 1990, CH and CL vehicles with the high-level interior trim package utilized the gold ornaments.
Starting in 2007, the gold ornament indicated that a vehicle had an all-Mack powertrain, i.e., Mack engine, Mack transmission, and Mack axles. This is its current usage.
