Perhaps someone with a 1941/42 parts book could help me with this, please.
I have a set of 'long' forks with casting numbers 66-5016, 66-5140, and 66-5146. As far as I can tell from my researches this corresponds to 1941 and 1942. I know they'll fit on any long fork models, but it's been irritating me that the parts book for 1944 gives different parts numbers!
