I can't tell you too much about FT's 727s, except they were all second-hand aircrafts. Most were ex-AA's -100 series. However, regarding their 707s, FT had seven total, all -320Cs. Four were -349C, one -348C, one -358C & one -399C. All the 707s were gone by April 1969. I'll have to do some research regarding the 727s. Regards.
