Light to dark shades of grey with white horns tipped with a darker grey. Glossy models were in production into the mid 1970's and possibly as late as 1979 as seen in the catalog. There are known glossy chalky models. Unknown when the matte models first appeared, but later models tend to have a very matte appearance.
1956-1957 referred to as Brahman Bull with hang tag.
This mold was inspired by a porcelain model sculpted by Edward Boehm. It originally had no mold copyright stamp, but the round Breyer Molding Co Copyright Stamp appeared around 1983. Some models will have a combination of B Stamps: on the back legs, horns and/or scrotum. These stamps lasted outside of the B Stamp era, and remnants of these stamps can be seen on the #385 models (still researching if they are on later models). The horns, ears and scrotum are separately molded pieces.
