It's a brand new Sony Keypad (for something, dunno what), made in Japan, uses white vintage linear Alps, and has some of the most unique doubleshots I've seen. The keycaps are mildly cupped, rather than spherical, I'd say a really flattened impression of the corner of a cube, that has been smoothed out (I have other keycaps with a similar impression shape).
Oh, and this was made sometime after 1982 (FCC date).











Interesting doubleshot molds



Now this is odd, these vintage Alps switches are plate mounted, but the plate is the plastic case. (now how am I supposed to remove one of them...
