Iowa Red Angus Association Special Run. The first 100 models produced had pinking on the nose, were numbered #/100 and came with a 'Big Red One' Certificate of Ownership from the Association. 200 models were produced with a brown nose (body color or slightly darker) variation and numbered #/200. There were also 300 models, with the brown nose, that were numbered #/300. Another estimated 400 brown nose bulls just have a single number written on the belly. This information was provided in Nancy Young's 5th Edition of "Breyer Horses, Riders, & Animals Molds & Models"; however, as the photo from a 1995 JAH shows, Breyer only made an estimated 350-400 models (research ongoing). Certificates were issued for the first 100, and the second run of 200, but not sure if they were released for the entire run.
These bulls may have the B Stamp, but not verified.
