the only other bike i'd say would be an apollo,from halfords , but it looks a bit better than that
When I read the initial post I was going to suggest the Halfords/Apollo GT style frame, I recall someone having one many years ago, and its was a pink/purple/blue ish colour.
EDIT: Also noticed some text on the seat stay nr the tripple triangle, the text looks familiar too.
Looking at this thread, this bike could well be a "Apollo", distributed by Halfords. Maybe their premium model with Deore DX?

Allegedly, they "licensed" the triple triangle design but I think we will never find out for sure...
@ bloodfire: GT definately did cable rooting. Truely internal just for the rear brake especially in the model year 1991. But as I wrote, the cable entered on the left hand side.
