For what this is worth, I thought I would throw it out and post it. It does not resemble Triploidite from other localities. Further, Triploidite has not yet been reported from Hagendorf. It is dark reddish brown and black and is probably Rosckbridgeite and Triphylite.

Note the old lable in the prov. tab.
