[Rockhounds] Question on Boracite

[Larry Rush]

Some years ago, I ran a Thumbnail mail group, devoted to the education, Information, and trading of Thumbnail sized minerals. One of the members was a fellow named C.Korpi.We had a nice exchange whereby he sent me a fine Bolivian Boracite crystal, in matrix.   TheAlto Chapare Mine was the world's best source of these, at that time. Does anyone here know Korpi??I no longer have his address.
The crystal I traded for, with Mr. Korpi, is a Terminated Orthorhombic crystal, lustrous gray, 20X30 mm in size, in a bed of Gypsum, total specimen size being  30X40X40mm.
Mindat lists this locality as being known for the large size of Boracite crystals, with a maximum length up to 27 mm.
Taking this at face value, and having nothing else to go by, including Dana, this means I may have one of the  largest Boracite crystals ever found.
I am quite bothered by this potential bit of information, and am really not too happy to be in this position.
Can anyone suggest how I can verify this, and if true...what should I be doing about it, in terms of finding the proper site (a museum?) to whom it can be endowed??
Thanks.....
