I've seen a YAS-32 with nickel plated keys and fittings (and no, it definitely wasn't a YAS-23 or 25) - the owner bought it in France back in the '80s, and was the first YAS-32E (which was the model number stamped above the Eb keyguard) of this type that I'd seen.
The 32E that came on the market in the '90s had an all lacquered finish and the tilting Bb spatula.
