I will not comment that seller.
However thatone looks verry verry well. Well I guest that it was real, but I think it still overpriced. That is not a 10.000$ crusader era sword, but rather a 17th century piece, slightly bigger than thoose landknechts schwerte. Nice piece, however certainly not a bargain missing its quillons.
Another thing, the crazy appraisals from that seller are taken out from Christie's auction catalogues for the year 2020...
The viking variant of the tokuba is just gorgeus! The essential piece for desert boardings.
