Willys Motors Service Bulletin #301 (Aug 19, 1955) has a numerical index of service bulletins. It will cross-reference the K-W number to the old K-F number. I do not have a list for the pre-KW bulletins from Willys-Overland, the highest numbered bulletin I have is #53-29 (July 23, 1953) dealing with the Hydramatics on the F-head. I only have about ten or so of each company. And then there were sales bulletins as well. I can get you a copy of #301 if you need it, but if you have Ben's list, I'm pretty sure that's complete.
