Buick used this shield in various shapes, changing to three overlapping shields "Trishield" with three different shield tinctures, gules, argent and azure in an annulet. The latest version with no colors at all. They at least started with relatively good style with the "Buick family crest"... though I didn't find evidence of that in a cursory scan.
