You guys are right! My bad! I failed to check for an official title for this board. I bought it used, and the previous owner had called it "Stormtrooper". I've also seen the RF87UW with black on dark grey caps referred to as "Stormtrooper" elsewhere on the internet. But I checked the box that it came in, and sure enough, it does not say "Stormtrooper" on the box. It is a Realforce RF87UB55 that has had black on dark gray caps put on it. I also did a dome swap, replacing the 55g domes with 45g domes, and I installed silencing rings, lubed the stabilizers, and put foam pads under the spacebar.
My wife handles the eBay sales. She is checking to see if it is possible to change the product description. If not, I think she can add a note to the listing to correct the things that are incorrect in the description.
Thanks for pointing out these errors! The last thing I want is to have a misleading and/or incorrect listing. My apologies!
