Not an expert myself, but I'll try my best.
WYSE - I believe WYSE is an older company from the 80s/90s that manufactured keyboards.
MOOGLE - From what I understand, a "moogle kit" is a set of key caps that complements vintage/older key caps of the same style so that they can be used on a modern keyboard. The moogle kit replicates size, color and any graphics of the vintage caps.
I'm sure other people will have more information, as I'm pretty much a newbie myself.
