year 2600

The name in the signature might be Kunimitsu(?).
Part of the date is "2600 year", which means 1940 (the 2600th anniversary of Emperor Jimmu).
The person you want to ask about this one is Chris Bowen ( http://www.ejapaneseswords.com/ ). He is probably the foremost English-speaking expert on 20th century smiths.
