I like the 'hammered' texture of these mid-century vintage cast aluminum dutch ovens - and I love the way these nest together, nice for camping! The lids are made to be used as baking pans as well, I think.
The larger pot is 4 quart size, 9 1/2" in diameter x 4 3/4" deep. The smaller pot is 3 quart size, 8 1/2" in diameter x 4 1/4" deep.
Both pots are marked Le Winter Appliance Co - Los Angeles. Both are much used though they have years of life left in them yet. And both pots and lids could use a good cleaning to shine them up a little bit.
