Every Newell is designed and built to customer specs. No two Newells are alike, making it impossible to get drawings. schematics for the 50 year old coach you are interested in.  When it was delivered to the original customer, it came with extensive build documentation  The engine alone weighs between 2500 and 3500 pounds. We just had our 40 year old radiator rebuilt. The cost ? More than 3000 dollars, and that was with me removing the radiator and taking it to the industrial radiator shop . Not saying these things to deter you, just commenting on  how expensive these thing are to maintain and repair. Many members of this forum have worked on older Newells and even repowered them with modern engines. They are a great source of help.
