It appears to me to be an earlier blade that was possibly put to use during the war due to the leather weather cover and the suspension ring. It will be difficult to determine the actual age because it is not signed. Bob may be able to give you an approximate age based on the fittings and style.
I like it!

Accurate kantei of a Japanese blade can only be done in hand-especially when dealing with an unsigned piece. The lack of any nakago deep patina along with the crispness of the file marks would lead me to believe it is a blade made during the end of the sword making era in the mid 19th century. Silver habaki usually indicate a blade make in the new sword era while gold indicating koto. However, I have seen numerous exceptions to this rule.
