All the sealed Klusons with covers similar to the machines shown have "Kluson" on them, at least all the ones I've ever seen. The ones that look like Klusons on lower Gibson models from the '90's and '00's that say "Gibson" are not Klusons, but Asian. I believe the ones shown here are as well. Unfortunately, the Asian ones I have experience with are poor substitutes for Klusons, which I believe are now sold by TonePros.
