Cherry M9. It was their "low-profile" switch — same size as the successor the MX, but most of the switch is under the plate. It does look like a reduced size M7, but it introduced changes to the shell that were re-used in the MX (removable lid with side retention clips and holes in the top to release it).
I should be getting one or two some time this year that I can disassemble for the DT wiki, but feel free to beat me to it (you could even enter the photos into the wiki photo competition).
No idea what the keyboard is, though.
