>Hi, a rhomphaia in very good condition was recently sold to a Chicago
>collector on EBay (the photo is still there). As this is a very rare
>item, it is a tragedy that its provenance will not be known. However,
>the new owner is willing to get a metallurgical analysis done on it, if
>it doesn't have to leave the USA. Can anybody help me find somebody who
>would do the analysis, or pay for this process?
