If there is anyone who can define "Museum Quality" it is Mr Wegner. He curates, possibly, the largest ship model collection in the world. That includes the Rogers Collection, ship models in the White House, Congressional offices, Naval offices and all other ship models owned in the US Navy. His definition is for the Navy and Smithsonian. Obviously, they have the highest standards. So, in his area of responsibility, he gets to define the rules.
I have interacted with Mr. Wegner on many occasions, and I can assure you that he is as informed, as anyone in the world, of ship model concepts.
