Hi Tom,
Yes, the interior of Kismet appear in good condition and original.
As you'll have seen from:
http://www.seahawk17.org.uk/description/cabin.htm#vberththe numbers and pattern of cushions above the V-berth do vary. Your boat does not appear to include the two square cushions that sit on the forward part of the quarter berths that help provide a full 6ft length for the v-berth, meaning that the v-berth are of child-size only.
The shelf/back-rests and lack of any form of lining to the cabin is standard, as is the forward anchor locker, and exposed bolts of the fore hatch and window framing.
