I have a couple 75S-3B manuals. Off hand, I don't remember the SB-1 and
SB-2 mods. One of my manuals which dates from before May of 1964 is
somewhat bloodied from mods I've made. The other manual from later that
year (which I wrote) is clean. I don't have a copier handy but can shoot
scans with my digital camera with lots of pixels.
