Recent "ish". Generally speaking, the increments only go up 1-2% per year in the CEA unless there's a new type. Not sure if Cook got an increase for -600.
$40k sounds like it might have come from the now retired Eagle Air (B1900D) or perhaps a very old Air Nelson figure before things improved there.
-edit-
I believe newly hired FO's start on year 4 ish pay if they have an ATPL or passes in all ATPL subjects, so not sure if the above numbers are actually year "1".
