[WTB] NOS/like-new Unicomp 104-key pre-2013 bottom row

[pandrew]

I prefer Unicomp keyboards with a pre-2013 bottom row, differences explained here:

I've been searching for a while on ebay, and I found a few, but all of them were used, and most were horribly yellowed, especially the metallic grey color keys are very susceptible and yellow non-uniformly.

So I am wondering, does anyone have stacked away any pre-2013 unicomps, that are new, or almost new condition?
