So far as I do know all F chassis 2, 3, 4 sequence have the identical filters (pictured final).
May your first image be that different unspeakable 2 sequence mannequin or the G chassis? It seems just like the F44 makes use of 2 filters like your first pic, however I am undecided of their orientation in realoem. The G42 does not appear to have been added to realoem but however they use an oblong filter with a nook lower out.
