Mark,
I'd recently looked into this, as Dave Siskind had given me one with the
brazed on stop reciever, for my '59 Jack Taylor.

Found some info at http://www.velostuf.com/
According to this, brazed on pivot stop receivers were '67 or '68. Turns out mine must be a '68 as it also says "PATENT" next to the cable stop, which was a '68 or '69 feature.
BTW The rear mech Dave gave me looks like NOS, except for a bit of wear on the inside of the cage plates and Simplex Criterium ball bearing pulleys. What makes this amazing is that according to Dave's records he'd put 17,732 miles on it.
