Now I've only flown on two 320s, but I know for the reasons above that it was a different seat.
The seats in row 1 of the A320 have the tray tables in the armrest. However, that's the same on the A319 or any other Northwest plane where the tray tables are normally otherwise in the seatback. Since there is no seat in front of row 1, there is no seatback to have a tray table.
This link will show you that the seats on the A320 have a width of 21" or 21.5" and a pitch of 36":

This link will show you that the seats on the A319 have a width of 21" and a pitch of 35"

This means that the seats on the A320 will ALWAYS have 1" more inch of pitch (distance between seats or legroom) than the A319 and sometimes also have an extra .5" of width.
The interiors on the two aircraft are identical for commonality. There may be slight variations due to age but I don't believe that the height of the seat is different universally.
