I bought two keyboads from the seller. These are AT102W alright, but his concept of "clean" seems to be flawed. I had to completely dismantle the two, and clean and swap key caps just to make one of them decent and useable. The plates are corroded in places and required WD-40. These are well used keyboards, and the tactile feeling is almost non-existent unless the leaves are tweaked to bring it back.
These keyboards were a nice week-end project and a good opportunity to look at what goes into a mechanical keyboard, but in the end, I've fallen back to using an older IBM rubber dome and a Cherry G84-4100.
