Oh, it certainly goes both ways and I'm not saying I'm right and you are wrong; simply a discussion.
I thought it was common knowledge that the entire miniature WAS painted between the pilot and series. Did it not go from white to gray/green? Also, the blue dorsal disappeared at some point between the pilot episodes and the series. I will have to pull out the Datin interview but I swear I remember him saying that it was repainted before the series started (but then again I may be wrong, lol).
