The purpose was originally to introduce all the products of the company CS Card Iron Works in catalog form. There is also a description of each, a clean black and white image and important vehicles incoming tables from which modelers can take the measurements for example the dump bodies. The book is clearly structured and has many interesting details about the car on.
I brought this book very much; I would highly recommend it! The CS Card Iron Works Co. Mine Haulage and Handling Equipment Catalog
