Only thing Reynolds are the main frame tubes. Fork and stays are high ten steel, and it is not double butted, straight gauge. I picked up a 1980 model this week myself. Found a catalog somewhere on line, but now I cannot find it....

1981 version was butted 531. Even then it had high ten steel fork and stays.

Your bike came with barcons, like mine. Bike originally came with Weinmann 700c concave rims. My rear is a replacement.

Mine needs quite a bit of work, and is missing some of the original parts. Fortunately, I have most of them in the parts bin from another Raleigh.

Kurt does have a catalog page for the 1979 model, and it clearly states high ten steel fork and stays. Go to the Headbadge for more info.
