Vintage Blue enamel dish with lid, plus Black pot - together with enamel plate

A nice little collection of old vintage enamel items.   The blue bowl has a lid and is in lovely used vintage condition.   The inside of the lid handle has a small piece missing plus some enamel damage on the bottom.   The black pot doesnt have a lid and doesnt appear to have any holes in it.   I think the big white plate is modern.   Please look at the pictures carefully and dont hesitate to ask any questions.
