Thanks for the reply - no, not the wheel reflectors, but the front reflector mounted on the top of the fork just below the head. We still have the red rear. Yes, that BMX-era fashion with anodized colors was likely going through my head as a racing pre-teen when I persuaded my father to buy this just as the mountain bike trend was taking off.

I'll share photos to the vintage mountain bike thread. Perhaps this post belongs there. The bike is lovely - the above photo shows one with the reflector sought but it's not ours, which is in exactly this condition.
