For sale is a very nice used dealers parts and illustrations catalog for 1929-1959 Chevy cars, including Corvettes, and both light and medium duty trucks. This is the catalog that a Chevy dealer would use to look up parts for customers but it looks like this one was almost never used, it must have been a spare. This catalog, with an effective date of April 1,1959, contains over 1,500 pages (all present) of part numbers as well as illustrations that are helpful in showing how parts were assembled. Although this book is in almost mint condition, it is over 60 years old, so if you buy it you should take care to support the spine when using it. This is a great resource for parts info for someone restoring or maintaining a pre-'60 Chevy product.
