They'll be magnetic valve switches.  Could be fun for someone looking for something unusual and for a project.

The keyboards on auction are different from the one in the other link. Keycaps are entirely different shapes, so it’s highly unlikely they’re the same switches. I’m not sure what kind of switches they have though.

It has identical alphas and alpha shapes with the same bars on the home keys as well as an identical layout with the exact same case.  I'm willing to state that they use magnetic valve switches.

All the keycaps are of different shape, including all the 1u keys. They have the same type of homing slots though, and the overall keyboard construction is very similar.

I believe Haata had a keyboard with those vertical homing bars that was brown alps but I may be confusing it with something else.

Also note that this style of magnetic valve switch uses a rubber dome so it's (reportedly) not that great. In the devlin KMX144 find thread I believe someone put BTC or keytronic springs on it to make it linear.

Switches seem to be different:




I’m not sure which two keyboards are part of this particular auction. From the original auction pictures it looks like they’re both the type shown on the bottom in this picture. (And I think the seller has a separate auction for the other one maybe?)

Turns out the auction is for one of each. That is, one ITW magnetic valve keyboard and one (Maxi Switch?) dome keyboard. Even though the original auction pictures show two of the dome boards.
