FINE AND HISTORIC ALSTONITE FROM THE FALLOWFIELD MINE,HEXHAM,NORTHUMBERLAND,ENGLAND.
Acquired by the British Museum from William Neville in 1863.
Passing, by exchange to Richard Barstow in 1981.
I acquired it for my collection in late 1982 until I parted with the collection in 1991 to Patricia and Lindsay Greenbank.
( WIlliam Neville who had bought W.G. Lettsom's collection sold his collection to Henry Ludlam in 1877 - who's collection is now in The Natural History Museum, London )
