This also came from the plant in Sydney.  It appears, as there are hinge marks on the back side of the teak panel, the plaque was likely a cabinet door.
The plaque is 33 x 13.5" .. the hull is 27" .. weight ~7lbs.

The hull does not sit perfectly flat to the board, never did. 

There are some hairline cracks in the rudder area and other minor chips and marks.  ..it has been moved and hanging since the 70's.

Also available on the local CL, so this sale may end at any time.
