If this helps you at all, Th red dye most commonly used in the 18th and 19th centuries was called turkey red. A bright red, just a smidge to the purple side. Can’t help with the Brother numbering system. Just google images of turkey red.
Before turkey red dye was developed, the most common red dye in this country was madder. You should be able to find paint chips for both of these colors in almost any paint brad.
