@Markw posted:The best article I ever read on this subject was CTT issue February 1990 that has a ten page summary of all the shell, frame, motor variations over the entire postwar run of the SF F3.
Ding, ding, ding, ding, ding!!!
Help yourself, Mark!...
And I was able to find that issue...moldy bouquet and all...'mongst the basement archives!
1990! 32 years ago! No wonder the cranial fog had set in.
Many thanks!!
