This page seems to be focused solely on lubrication, and I don't know if any comments are made about the switches themselves. I've tried to contact the author in the past, and never got a response.

Since this is a Korean website, the odds are reasonable that this is a Gold Star Alps keyboard. In which case, there is a possibility that SKCM Brown in Korea is a regular tactile switch, i.e. their equivalent to ivory or orange.

Until we find more examples of this, there's nothing we can really confirm about it. I did notice that post years back. It'd be interesting of Goldstar Alps had their own tactile variety. They did use some of the standard Alps switches, like SKCM Blue in the DC-3014, and SKCL Yellow in their localized IBM Multistation keyboards as well as SKCL Brown.

Bit of a mystery though. Would be nice to uncover more about this one.

I don't know if the author just doesn't respond to anything short of fluent Korean, or if he's disappeared without trace, like so many people.
