I know I'm a little late to the party, but I bought one of these new in '96. Actually, two of them. I had a friend who was a dealer here in Mississippi, and he told me there were 4 colors:blueburst, blackburst, redburst and greenburst. I have never actually seen a red or green, so those may just be a legend. But I own a black and a blue, and I can verify that they did indeed come from the factory that way, and the finish was the satin-type finish common on D4's. I don't have these two at my house right now, and I don't have pictures of the labels on my inventory photos, so I can't address the 'HP' designation. As for these being only from a certain distributor, I bought both of mine from 2 different local, independent shops, and I know for a fact that the blue one was ordered directly from Guild in Westerly. If anyone has any further info, especially on the existence of the red and green models, I would love to know.
