I have to assume that Specter is the correct spelling. Specter means ghost or apparition. Spector isn't a word (although wikipedia tells me there is a Bass Guitar company called Spector, so maybe the original breeder of the 'Spector' is also a bassist?).
More on topic, that is one sweet snake, I would definately see what that can produce. Looks more like a morph than most morphs nowadays lol. Here's hoping he proves out!
