The ESC-row grey one like in your picture is from a G80-2000, arguably one of (if not THE) rarest production Cherry keyboard. They haven't been remade, except in a small GB in the early days of OTD. Your chances of getting one are pretty much zero unless they are remade by GMK, sorry.
The B-profile (bottom row/shift row) white one can be found on G80-2100s, which are rare and expensive, but sometimes come up on the classifieds.
