I want your maximum scrutiny on this blade here. It is alleged Kyu Gunto, but the length of the blade and the apparent looseness of the nakago in the grip throw me off. It is firmly of wakizashi length at a mere 21.5 inches for the nagasa and with a sori of .25 inches. It is signed "Nobuyoshi" but that is the word of the seller. I believe the grip and blade itself are Japanese but with its slight looseness (which may be due to a poorly sized mekugi), there might be a possibility its a put together. It does have both rear and forward seppa. The scabbard does fit it well, but it is about four inches longer than the blade itself (though internally, it appears to fit tightly).
I suppose I am asking a few things:
Were Kyu Gunto of non-katana sizes (even at 21.5 inches)?
Do you think this is a put together?
What is the smith's name?
Whats the possible age range for this blade?
