Willing to pay a pretty penny for these, either from the groupbuys or from an old 1800 keyboard (must be ABS doubleshot or OG PBT, if that even exists, and must not be shined).
(the blue ones are the most important in this last photo)
most important keys are: r5 numpad zero, r1 delete & end & pgdn, r2 1u minus sign, r3 1u plus sign.
If you have any of these keys or sets hit me up. Thanks!
