Original 1946 thru 1955 Buick Wholesale Parts Guide Book. Book was issued in 1956 but has NO 1956 applications. This Book was distributed by Buick to Garages and Body Shops to simplify the ordering of Parts from Buick Dealers. It contains the page number, illustration letter and Group number of most Buick 46 to 55 Car Model pieces to ease finding of Part Number in Parts Book. It does NOT CONTAIN any Part Numbers. It is well illustrated and easy to read. Book measures approx. .75" thick. Very informative and useful tool for Collector, Enthusiast or Car Owner. It is in good condition for its age with normal wear, soiling and blemishing from years of use in a Shop [see photos].
