Lake Brown is approximately 20 kilometres south-east of Mukinbudin.
The meteorite was discovered by N.A. Stuckey in 1919, and later recovered by H.G. Stokes, who presented the specimen to the Western Australian Museum. It was studied in 1921 by E.S. Simpson, and a published report on his findings by the British Museum in 1929.
The meteorite is 43cm x 38cm x 35cm, 9.75kg, and a specific gravity of 3.505.
The fractured surface is light grey in colour, and stained in parts by iron oxide, from oxidation since falling. The approximate mineral composition is nickel iron 7%, troilite 6%, olivine 36%, pyroxene 38%, felspathic material 8%, and ferric oxide, water, etc. 5%.
The reference describes it as an intermediate hypersthene-chondrite of the Baroti type.
