vintage doll size robin's egg blue enamelware canner pot or baby bottle boiler w/ wire rack

Cute old 'working' kitchenware for a little girl and her dolls, 1940s or 50s. This is a enameled metal pot with wire rack, probably made to hold tiny baby bottles or tiny doll size canning jars, something like that. We have none, just the stockpot style pot with lid and wire rack.

It's worn and used as you can see from the photos. The pot measures about 4 1/4" in diameter x 3 1/2" deep, and the wire rack is made to hold a jar or bottle 1" in diameter.
