Ovenex starburst texture round ring spring form baking pan, 1930s 40s vintage kitchenware

Vintage Ovenex starburst texture baking pan, a two part ring mold, 9" in diameter x 3" deep. This is 80 or 90 years old, nearly an antique now.

This has been used, but looks pretty good aside from some rust spots on the ring below where the insert sits (can't see them till you take the pan apart).
