from time to time solid aluminum models Boeing 314 Clipper Flying Boat in 1:50th scale appear on ebay and usually sell in well in excess of 2,000. Gary Fields made these in the 1990s and they are extremely well done with a great stand.
I was reminded of this model when a friend sent this link to a little remembered flying adventure involving the airplane at the outbreak of WWII
