Here's a photo of my Northwood 301 (this example is called "Apple Blossom" by Carnival collectors because of its enamelled design). The measurements given for this bowl by Dave Shetlar & John Madeley are:
4 1/2 inches wide, 2 1/4 inches high.
I have studied #662 in my "Stretch Glass" book where the images are much bigger - it appears to have more panels / "optic rays" than JJ's bowl. The measurements of that cupped bowl are:
7 5/8 inches wide, 3 1/2 inches high.
Now here are two photos of my marigold bowl. It is flared, as you can see. The diameter is 7 inches (17.5 cm); the height is a shade over 3 inches (8 cm); the collar base / marie is just under 3 ½ inches (8.5 cm).
