Only 2 mei in the signature.  The first character has me baffled.  Second character I am guessing  'mune'

 

Thank you in advance.

There was another sword by a similarly-named smith posted very recently. I don't know if it is the same smith. Often these WW2 blades were produced in assembly-line like conditions, so the signature may have been inscribed by several people working under Yukimune's supervision, which may account for discrepancies in the way of signing.
