Sorry to read this.
Like Ali said, the factory never made a black one. Most were silver and a handful were red.
The good news is that they are rare-ish so if it turns up then someone on the board should raise it.
The bad news is that they are mechanically very similar to the Superlight so may be broken for parts. It may be worth registering your interest with breakers (or ebay searches) for some of the more distinctive parts - eg high level pipes, single seat unit.
Edwyun has an excellent site that highlights the differences.
