RE: The common-ness of WMP compared to blue sparkle. I only want to suggest that blue sparkle is THE most-common of all the wrapped finishes. I'm almost sure of it. WMP is not as common, but it was a popular finish because of the association to Buddy Rich.
The set WMP set that jp was looking at was a BEAUTY! It had the right kind of yellowing to it -really more of a patina than a fade. And that's sometimes the cool thing about WMP. When the drums fade to that beautiful vanilla cream color, then all is well with the world! ;) And when the drums are kept together and patina the same way together, it's like having a custom color.
That WMP was nice, man! All the shells were stamped in red ink and all the drums were matched. They looked to be in extremely good shape and have obviously been well-cared for over the years. No alterations....etc. The hardware didn't appear to be hacked out at all -nothing stripped or worn from over-tightening, etc.
I think a grand was a fair price for a kit in that kind of shape to a guy who really wants a nice vintage set of drums. Even if it's just the shell pack, it's in such nice shape and completely matched. The seller is apparently a good guy, too.
If jp was planning on flipping the kit for a profit, then that wouldn't be the greatest deal, but if he falls in love with them and gets hip to the Ludwig mojo, then what's that worth? A million? Burger Kin
I usually don't go by the common-ness or rarity of the finish, anyway. I love blue sparkle no matter how common it is. And when I found my Deluxe Classic blue sparkle kit, it was in such nice shape, I bought it even though I don't really dig those sizes that much -because it was so beautiful. It was like having a kit from a time machine! That's why it sold more than any other wrapped finish.
All things considered, I think the WMP was/is the best deal on the table.
