As Evanelpus said - the 700A aircraft were built at Chester for the North American market and were mostly(though not always) ferried to the US in "green" state - i.e. unpainted and unfurnished for completion.
700B aircraft were delivered from the factory complete painted and fully furnished for the rest of the world (even to the lengths of stocking the liquor cabinet and soap in the toilet).
No such animal as a Hawker 700 existed during production. It is likely a convenient tag to group the lineage following the Hawker 800/850XP/900XP/750
marketing tags adopted by Raytheon then Hawker-Beechcraft.
My recollection is of standard wing configuration between 700A/700B models.
