Dear List,
I have a very nice 10.74 gram slice of the Eucrite NWA 1836, also known as
the "Twisted Sister" for sale. $375 [includes priority mail/insured
shipping]. This represents a significant savings per gram for this rare
meteorite. Please contact me off list for picture, more info, etc. Willing
to negotiate if you think the price is too high. Below is the write up from
the Met. Bull. Thanks for looking. Take care
