I've seen a '57 300C speedo on ebay (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=1825900061) and the seller says : (..) This is an assembly line unit, as if it were service replacemant the "TENTHS" numbers would have to be red (..) Is it true ? And same property on other speedo ? On my Imperial the (non working..) speedo has red "tenths". -- Philippe COURANT (Pau, France) Imperial 57 Crown convertible Buick 58 Roadmaster sedan - American Car Club de France (ACCF) : http://www.accf.com - Chrysler Imperial France : http://www.ifrance.com/c-i-f - Cadillac " Standard of Excellence " : http://www.ifrance.com/accf-cad - SportsCars : http://www.ifrance.com/accf-sprtcar
