This is the (MB72) Hovercraft SRN6 from Matchbox.

Collectors Note: This was released 40 years ago in 1972. It is one of Matchbox’s rarest and least produced castings, with only three variations of this one design every being made. A different hovercraft was later produced.  

This is a true cross-collectible, so if you collect Hovercraft, Watercraft/Boats, or Matchbox this will be a very nice addition to your collection. (1:64 Scale)
