Here's the 1986 Prelude. The catalog photo shows "Bright Blue", but it was also available in "Gunmetal"...
The frame is Columbus Tenax double-butted main tubes with chrome-moly stays and forged dropouts with eyelets. Derailleurs are Sun Tour Cyclone (front and rear), and the crankset is SR SXC-200, 170 mm forged alloy with 40/52T alloy chainrings.
Very nice score.
