I read the article as defining museum quality by Mr Wegner. Seems we are being a bit picky. If you read his publication, "Fouled Anchors", available online, you can get a sense of his expertise. He, almost single handidly, took on the Government, the Navy and the City of Baltimore, and proved that the Constellation in Baltimore harbor was not the 1797 frigate but rather, a sloop of war built during the Civil war era.
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.
