I'm a designer for a small factory that builds custom machines (one at a time) and we supply spare parts for everything we have ever made since 1938, when the company started. I realize that custom machine building is MUCH different than assembly line production, but our stuff has evolved over the years and we have 9 long established model lines, for which all the drawings exist, all the documentation is still here. The major tractor manufacturers have all of their drawings, casting molds, etc, but some discontinue parts after 10 years or 20 years. So what is reasonable to expect?
