I have an old alps keyboard (NTC KB-6251) that I wanted to get going again, but I have misplaced the F1 through F4 function keycaps (see picture). I do have the casing/cable too, just not on in that shot.
I have the 4 desoldered switches and can reattach them no problem, but I'm looking for a cheap way to get replacement doubleshot caps for those four keys. I'm not too picky on colour, but would prefer something similar to the originals; if that's not possible I'd take black/whatever.
Let me know if anybody has these keys for sale and what price for these four. Thanks!
