Dear John,
I believe your decals are 74-75 reproductions:
but they are pretty good repros. The error is in the 2nd line of "Butted Tubes, Forks, and Stays", as the kerning is incorrect, so the "T, S, Y' don't align on all 3 lines. There are a few other minor errors - contact me offlist for more details.
This type of decal is PRECISELY from 1974-75 Reynolds 531 decals, since reynolds became 531(R) in 1976, and (TI) Reynolds in 1976/77.
John, your type of decal was used on Raleigh/Carlton models (Professional and International in 74-75, and in 1975, the Competition, too.)
I also have one of those NOS decals, and made some reproductions from my NOS decal. My purpose was to make them for my restored 1974 Raleigh Bike Collection, including this bike, my masi-champagne international :
