I have a blue '73 Pro and two '74s, one blue and one silver. All have the CC cutout in the shell. Also, all have "rapid taper" non-crimped chainstays. I've never seen crimped stays on US market road versions of this vintage. The '73 has a short serial number that starts with the letter A. The others have long serial numbers that start with W. Interestingly, one of the '74s is a centimeter longer in the top tube that the other two, though all three are the same framesize.
I had a '73 Pro track that also had the CC cutout. Raleigh replaced the frame after a few years with a '78 model, and it too had the CC cutout. The cutout was stamped, often distorting the BB shell. It was a true Raleigh feature. Interesting design, poor execution.
Speaking of execution, the silver '74 was executed two days ago when it took the brunt of the impact from a Toyota that ran a redlight. I made out with two more broken ribs. The Pro has three bent tubes.

\r?\n> I've resigned myself to the fact that I may never know the actual year =
