Ok, I found the full history now; in 1996 Thomas Wiegand and Marcel Christ from Germany bought the molds
and the car DB Roadster 1 from Jan De Buyser from Belgium.
They named their company RSC Hunter. The company Hunter Coachworks put the molds for sale in 2002, in 2009 and again on 31 December, 2011. August 2012 the company was sold to David Alcraft from GB.
Hunter Coachworks made 1 car and produced 5 kits.
So as you said this car is the last built, I think it's the only produced by Hunter Coachworks, in Hannover, Germany
