Jerry- My understanding is that the Fuji HiTen tubing was basic carbon steel, 1020 or 1018 or the Jap. equivalent if I had to guess. Those early 1970s S10-S's were quite heavy for a bike with lots of alloy parts, 29-30 pounds by my memory. This would make sense if the frame was thick walled as HiTen frames usually are.
Now the Val-Lite tubing used in the mid priced Fujis of the early 1980s was much nicer and lighter stuff.
