The West Coast mirrors that most smaller than one and a half ton trucks used were referred to as Jr. West Coast mirrors. Most were chrome and had large chevrons on the front side, sometimes painted yellow. Suburbs used them; I liked the look and functionallity and installed them on my 64 VW panel in 1964. I really don't like the convex passenger side mirror for backing situations, but one glued to a West Coast mirror works well for checking side traffic.
