I have one from the same year. It's a criterium sort of frame, with 74-degree head and seat tubes, 41.5 cm chainstays. Mine is very nicely constructed; equal in quality to the more common Competition model, maybe better, I'd say. The "fade" paint scheme is, sadly, very 80s. Check out Mark Bulgier's catalog archive, and look at the '84 Raleigh catalog -- the frame is pictured there. I can send you a spec sheet, and the catalog from Michael's Cyclery in Ames IA, where I bought mine in '85. It cost $225 then, and indeed, came only as a frameset; I built mine with Campagnolo SR "reduced" group.

This is a Nottingham-built frame, from the years when the Competition and International were already outsourced to Japan.
What size is yours? Mine's a 57 c/t.
