One mass of 54kg was found 12 miles NW of Bencubbin, described, with analysis, E.S.Simpson and D.G.Murray, Min. Mag., 1932, 23, p.33. Analysis, A.J.Easton and J.F.Lovering, GCA, 1963, 27, p.753. Mentioned, A.D.Nininger, Pop. Astron., Northfield, Minnesota, 1940, 48, p.558, Contr. Soc. Res. Meteorites, 2, p.227 (M.A.8-54). Another mass of 142lb was found in 1959 or 1960 at Mandinga and is considered to be part of the Bencubbin fall, M.H.Hey, Cat. Met., 1966, p.48, Spec. Publ. West. Austr. Mus., 1965, (3), p.21. A similarity with the Patwar meteorite has been suggested; a new class of enstatite-olivine stony-irons is proposed to cover these two anomalous meteorites, G.J.H.McCall, Min. Mag., 1965, 35, p.476, G.J.H.McCall, Min. Mag., 1966, 36, p.726. Possibly includes Korrelocking, A.L.Graham et al., Cat. Met., 1985, p.68.
