gendaito real nihonto /mumei

[sc72]

I bought a book on modern Japanese swords and in the meantime that it will reach me I ask you in general:

assuming that we find ourselves in front of a "gendaito" katana (...here meaning by this term a "non-industrial" Japanese sword, but a real nihonto handcrafted sword by tamahagane) can the fact that it is "ubu nagako-mumei" (and without any mark or hallmark) make us lean or say something more? ...for example the production period, pre or post 2 GM (es.. sword from 30s or from 50s?) or something else? I think the koshirae is irrelevant as it is replaceable on blade (it could be military gusto or Edo period, raplaced/changed). I have read everything and the opposite of everything on the internet Thank you

I think I understand that non industrial nihonto swords made by craftsmen from 1960s to the present day are always signed, but does being "mumei" imply anything to those swords gendaito that are presumed to be from 30s-50s years ?

I read somewhere (I don't remember where ....on the internet) the statement of a guy who said that the "non-industrial" mumei gendaito sword would only be "unsigned" only if they had forging defects.

while others say that being a mumei sword could also be possible for swords from the 30s-40s period

Just my two cents, however I think the answer to your question is no. The condition (state of the rust, shape, number and style of nakago-ana, file marks, etc.) will tell you much more than a nakago just being original and mumei.
