Offered here is a rare Leading Edge Model SKM-1030 mechanical keyboard, made in Korea. I have seen a similar keyboard with the same model number but with Se-Jin listed on the manufacturer's label. That board was described as having Futaba linears, so I can only assume it is the same for this one without actually taking it apart. Key action is smooth and softly "clicky". No jamming or gumminess in of any of the keys.
Condition:
Untested, but appears to be well taken care of. Light surface soiling associated with vintage use on the tops of some of the keys. I have not tried to clean this board in any way.
Thanks for looking!
