Hmm...
Interesting find.
Seems to me to be exactly the same design (but in different colourway) that John Atkins wore when he was sponsored in 'Cross by Carlton Cycles in the early '70s.
See CR site for a pic of the esteemed John A here:-

Don't recall any UK domestic pro' being sponsored by Raleigh in these colours at that time, and don't remember any examples of the Raleigh jersey being available either (though the 'Carlton' version certainly was through Raleigh 5 star dealers as I recall - also manufactured by Lutz, who made most of the UK club jerseys at the time).
