I cannot clearly make out the shape of the contacts on either yours or Sandy's, but I imagine that "Type II-SS" and yours are both the same as Type T5, with some manufacturing variation. I'm having trouble with the shapes:
They're probably all Himake AK-C5 (D5 when linear). Strong Man made extensive use of those style switches, though often we don't get to see inside them, so we never know which specific variety they are. It's always great to have another data point, so thank you! I shall add this page to the wiki as a reference.
As a note, AK-C5 is officially noted as having a white slider, so your white sliders are correct; it's these grey ones that don't match up:

Note that Sandy's Alps page was removed (as I recall) due to containing outdated information. He's no longer interested in clones, and the DT wiki should be considered the most authoritative on clone switches, based on the comprehensive data from alps.tw and additional research.
What I'm still desperately seeking is confirmation from companies who used these switches, such as Ortek, MacAlly and ELSA Communications, to confirm whether they did all buy Himake/Hua-Jie switches. Focus appear to have folded, and Strong Man are long gone, and they were big customers of them.
