to answer the question - absolutely!
this blade is exceptionally beautiful, in hand one can see all the features of nanbokucho Bizen. it reminds one of the work of Kanemitsu rather than anything that came out of kozori later. ubu in every sense, with the marks of a hard life still intact. whomever carried this sword cherished it from the day it got damaged - it was papered in this condition. after pouring over the blade, remove the nakago and find it is signed and dated! not only beautiful, not only proven, but rare with historical evidence. it may not be pristine but to me it is perfect! i should be so lucky to one day own such a sword!
