If existing patterns are anything to go by, the model should begin KC_-.
Also, being a typewriter, you're also likely to have a double-action switch in there somewhere. Mechanical shift lock is also possible.

Unfortunately i got rid of the typewriter, but i guess it was made sometimes in 85, since there is a 84 on the PCB and a sticker with 1985 on the display Part that i kept:

The switches are all the same, no special ones in this typewriter.
They feel a little wobbly, dirty and slightly tactile.
