Right, it was probably purchased as a Spoiler in 91 with the addition of the quick tone switches. I suppose it could have been numbered as a D just as easily. It's a nice bass, and it will be interesting to see where the money ends up on this one. They don't show up that often, but previous ones that I have seen usually finished around $1500. I think maybe the use of the Europa name has them valuing it higher. Odd that such a little thing aids the value so much.
By the way, that first question on the listing was mine. You can tell by the typos...
