Apparently, it is a rubber dome with slider keyboard, made by Micro Switch.

The form factor is commonly called "Unsaver", because it is larger than a "Space Saver" (https://deskthority.net/wiki/IBM_Space_Saving_Keyboard).
From what I can find, there exist Model F (capacitive buckling spring) and rubber domes, but no Model M (buckling spring over membrane) in this form factor. On the Model F "unsaver" the angled section with the function keys is as wide as the keys below.
