I found a kit locally for sale that I hope to find more info on. I'm getting a great education from members of this forum.
The seller says it's an XP8 kit with Keller maple shells. It's the 4 drums only (12, 13, 16, 22) in black. It does have the memriloc tom mounts and such and the badge is opposite the tom mount. It looks to be clear laquer on the interior of the shells. The BD hoops match the BD in color. The wing screws on the tom mounts have the "R" in a circle (dull finish).
Is there a definitive way to tell if they are indeed XP8 Keller shells? Do I just look at the bearing edge and count plies? What might it be worth if in what is considered good condtion? I will check on getting some pictures but wanted to start here.
