This is a 3 piece serving oven. It's meant to be a bun warmer. The inside basket lifts out. This basket keeps the rolls away from the hot outside so your buns won't scorch. This aluminum piece has "BUNS" in black with a lady in a bonnet serving the hot rolls. The handles are also black which makes this aluminum silver piece so attractive.
It has MIRRO on the bottom along with made USA. It's very clean and in good condition.
