Be careful with that statement- Reynolds never specifically stated 501-
"REYNOLDS 531 CLUB SPORT transfer, a cycle bearing this transfer has top seat and down tube BUTTED in REYNOLDS 531 and head tube, BUTTED steerer. TAPER GAUGE forks, seatstays and chainstays manufactured from specially cold worked chrome Molybdenum tubing. Designed for fast sports and touring."
So, while it doesn't specify 501, it does specify CrMo.
