Falcon MR-20 (?) orange derailleur main image

Nothing surprising here - except the extremely lurid colour. As Yogi Berra might have declared, it's like déjà vu, from the fluorescent 1980s, all over again.

I am struggling to find good information on Falcon derailleurs. I think this, short arm, model was called MR-21.
