thanks for the comments so far.
Mostly I'm thinking of changing the components because I think I am in a "period-correct" mood or phase right now 8^)
the drivetrain and brakes really are fine.. so changing them is more ..whimsical?? though for no real reason I am not a fan of the 2 piece cranks where the crank and spindle are one piece... mostly because I'm a square taper spindle fan . the handle bars are a bit beat up.. maybe the PO had scott clip on aero bars mounted. I forgot about 3TTT, I think they would look good and fit in with the character of the Raleigh.
