You should post some photos of it.
Yes, lots of companies have disappeared. Keypot (KPT), Podworld, Hearst, and so many others have vanished. Nan Tan (who were a prolific keyboard manufacturer) is now part of Clevo, and I doubt we'll get anything from them now. Focus's website is still up, but their sales mailbox has been full for well over a year, and their news page hasn't been updated since the middle of 2011, so I have no idea what's left of them now.
Cherry have long discarded most of their data on the M6/7/8/9/10/11, though Ed Ferraton in ZF USA did find a spec sheet for the M11 switch that was only very recently discovered (no-one has M10 or M11 in catalogues). SMK were rude, and Alps, Futaba, Sejin (Futaba's manufacturing partner), NMB, Forward and various others have completely ignored me. I'd love to get confirmation from NMB of the acquisition of Hi-Tek Corporation, and the approximate date, but no luck so far.
There are a lot of companies I want to query about Alps clone switches, to see how many are able to confirm that they did indeed use Himake/Hua-Jie switches, i.e. am I correct in that no-one else used the same numbering styles? These include Focus (unreachable), Ortek (no response), ELSA Communications (seemingly now iRocks -- deliberately unhelpful) and MacAlly (also unhelpful).
Companies who deserve a gold star for actually being really helpful include Monterey International (who actually told me about Hua-Jie and confirmed that Monterey switches are SMK) and Chicony (who told me about Aristotle and also confirmed Monterey switches are SMK).
The only company who has ever confirmed the brand of Alps clone used is Monterey. 002's MiniTouch (made by Monterey) has switches with two numbering styles, appearing to confirm that both styles are Hua-Jie. My current samples from Hua-Jie match another, much less common numbering style. Collectively the implication is that most western keyboards with Alps clones used Himake/Hue-Jie switches. However, I'm still deeply uneasy until I can get more concrete confirmations from companies such as Focus, Ortek, MacAlly and ELSA who used these switches. This is where it would be far better to have native Chinese speakers contact these companies.
