The ONLY metal container that I can think of that didn't have pretrochems or paint in it that fits the smaller of the two is cookie tin, the one Royal Dansk uses for their rolled up, chocolate filled fancy ones. Not sure if they'll take the heat though, and you'd have to add a bail.

For the larger one, I've got some kitchen storage cannisters that are that size. 1.7L, stainless steel, fairly inexpesive. Downsides are they thick walled, so heavy and they take a while to get hot, and the lids are glass.
