Is there a picture?
The Dolch 486 is new to me. I saw one on eBay that has doubleshots.
If the layout is not like a G80-1800, then it is not doubleshots. "Big-ass" (backwards-L) Enter key, then it is Cherry MX Blue switches but pad-printed key caps. If there is a trackpoint inside the keyboard, or a trackpad, then it is not doubleshots, but scissor switch.
