Owen -
I believe the intent of our online
Service Index project is to go back as far in time as the available resources permit. With the addition of sufficient
Technical Letters, we could go back all the way to 1920 for the 1st Series Six in that one category.
To digress for a moment, the 1920s clearly provide the best example of the notion that Packard's
Series classification was independent of calendar/model year. The first 1st Series SIX was produced in 1920, but the first 1st Series EIGHT didn't come along until 1924. However, the significance of Series designations began to fall by the wayside after WWII.
As a postwar
(and primarily V8) guy, perhaps I take the scope of the factory shop manuals of that period for granted. Thanks for the explanataion of Packard's evolution of the shop manual; it affirms the picture that was beginning to coalesce in my mind. I'll watch out for that as I add
Recommended Literature links to the prewar
Model Info pages.
BTW, in your previous reply to
Mal, WRT to that
Reference Book, you wrote:
Quote:
...you can loose context and often can not easily determine what series and model the material was pertaining to
Heck, I find that to be the case even WITHIN the context of some of the original
Service Letters/Counselors - LOL! One objective of our online
Service Index is to help clear that up. Alas, while I've been able to backtrack cited part numbers, that's becoming more difficult as we are still missing some editions of the parts books from the immediate prewar period.
