Is it a word processor? I have something that is very similar if so. The caps are pretty hard to pull off and they're quite fragile. Feels linear but mine has an extremely scratchy and stiff key-feel.
It's not mechanical, but semi-mechanical. The keycap is held into a barrel, which presses down onto a metal leaf spring, which bends and actuates a conductive (linear) rubber dome over a membrane. Very odd implementation, but I believe that it was also used on some terminal keyboards.
