"B" model Macks are highly desirable trucks for truck collectors (the big kind). They can cost a small (or large) fortune. Some restorers buy up hulks and parts to help in their restoration businesses. Yesterday, I passed a "B" in Lansdale, Pa., that was being used as an advert in the parking lot of a trailer mfg company, it was a twin rear axle (screw) tractor and in very good condition. Have also seen a few "B"'s (mostly dumps) in and around South Jersey, so a few may be appropo for today. Just make them shiny. Joe
