After its introduction in the late 1960s Fred used his T/D "B" Riser almost exclusively... It was cut down with a lowered arrow shelf similar to this other personal recurves from the late 1950s and the 1960s.
While you might find 1970s and 1980s promotional photographs of Fred with a bow other then the T/D B Riser, you might experience difficulty finding successful hunting photographs of him with other bows.
