My question arises after finding a b/o badge on a set of drums with number 1127323. Using the list on this site it dates 1976, and the new Rick Giers guide is 73-74......how could there be such a discrepancy in years between these two guides? Are there other Ludwig guides as well?
In Part I of my guide I discuss the strengths and limitations of each of the existing guides. Hopefully my explanations provide a fairly complete picture of the guides based upon the numbers used to create them and the ways in which they are (mis)interpretted. Only Rob Cook's guide made much of an attempt to address the Blue/Olive badges of the 1970s. His numbers were influenced heavily by information from Paolo Sburlati. There is one particular set in Paolo's book that causes more drums than seems appropriate to be labeled as from 1976.
In Part II I describe the methodology that I used to develop my guides. The discrepancies between the existing guides and mine are primarily the result of a considerable difference in the amount and reliability of the data used to develop them.
Reread Parts I and II carefully and see if it makes more sense to you. If not, feel free to contact me directly or on this thread for additional discussion.
Mike, Kevin, Bun E - Thanks for the kudos.
