just picked this up today at the local flea market.nice engraved leather cover,with steel trim.thing weighs 10 lbs.hundreds of bulletins even dyno sheets for v8 & v12`s tried to post pics but said they were too large. i will try to modify them?
One interesting thing about these, which were used for bulletins issued from 1938 to 1948 and a little beyond... They are looseleaf with pages numbered in accordance with part number system, and as new information was added, new sheets replaced the old ones and the old ones were discarded. There should be a sheet up front listing what you should have as of the last date the thing was maintained. This system, naturally, led to some obscure information on seldom used parts (Like Denver heads) disappearing as late model stuff was increased. I found that every copy of this thing I find, thus, has some info that is not in other copies I have. I have one super-fat one, the rings won't even close, in which the parts guy painstakingly kept everything, with early sheets stacked with newest 1949 one on each subject! Dyno sheets are major high points, as are the car minimum performance standards listed in the "performance services" section...which is missing from most of these! The variants in these are endless. On top of that, the Canadians issued there own version...which was largely of Canadian composition, not just an adaptation.
