I found this on Griswold;

Griswold Manufacturing. Griswold Manufacturing (/ˈɡrɪzwɔːld, -wəld/) was an American manufacturer of cast iron home products founded in Erie, Pennsylvania, in 1865 that finally closed in 1957. For many years the company had a worldwide reputation for high-quality cast-iron cookware.

For a number of years Lodge was known as the only US foundry still making cast iron cookware. There are now several smaller companies in competition with them.

Lodge catalogs what we called the Cornbread Baker as a Griddle. Many local names abound. There is now a differential between a Camp Dutch Oven & a Dutch Oven. What they call a Camp Dutch Oven I always just called a Dutch Oven. Their Dutch Oven without the provisions for putting coals on the lid we called a Bean Pot.
