Phil, thanks for your input on this. The reason I was asking the question is that Winton Engine Company and Cleveland Diesel produced more than 300 models of diesel engines and other equipment within their numbered designation system (their engine models were generally named for the engineering project number). It probably is something that needs to be compiled before the knowledge base is lost. Maybe someday I can devote some time to it, but I wanted to find out whether anyone has already done it so that I do not waste time putting together something that already exists.
