We bought this DO in an antique shop in Ponchatoula Louisiana about 2002.
- The lid’s handle is tapered from large (with a button) on one side to smaller on the other.
- There are self-basting nipples in a evenly spaced grid pattern and extended lips on both sides to cover the two pour spouts.
- Marks on the bottom are:

MADE IN USA

The Cast Iron Collector says:
Birmingham Stove & Range Co. – Birmingham, AL
All BSR
– If heat ring, unbroken and inset. — [Yes]
– Lids have pour spout “ears”, even those supplied with dutch ovens. [Yes]
and
Lodge Manufacturing Co. – South Pittsburg, TN
1930s
– ¾” high size number at 12 o’clock [Yes]
– Lids have grid of pointed tips for basting drippers. [Yes]
1940s-1960s¹
– Inset heat ring with 3 notches at 9/12/3 o’clock. — [No, the heat ring is not broken]
– Later, letters denoting pan type, e.g. “SK” skillet, “DO” dutch oven [Yes]
– 
Lids have grid of pointed tips for basting drippers, size number and diameter or pan capacity incised on underside [Yes]
After ca. 1960
“Made In USA” added at center [Yes]
I conclude it is a 1930’s Lodge based on:
- the grid pattern of the basting nipples
- the size and position of the size of the CO
- The “DO” below the size
- the MADE IN USA in the center
- the bottom looks just like the bottom of the skillet linked to the Lodge After ca. 1960 category.
- BUT – The lid has the pour spout ears…???
