I remember this bike from my youth, it was around £180 in bout 1985ish, yours looks in excellent condition. It is indeed 531 main tubes only, the saddle is new, but the brakes, gears and possibly chainset (if it's SR) are original, as possibly are the wheels.
I think it ran 73 degree parallel frame angles, and was one rung down from the Record Ace, which had 531 forks as well, and (I think) Campag Gran Sport gears - otherwise similar.
For Sale Brodie Energy Frameset. Small 14”. Great quality kid’s retro. & FRM fork
