Hello all,

 

I need help translating the signature on my katana blade.

 

I think the first kanji might be 

内

any and all help is much appreciated, and thank you in advance!

Max,

if I see this right this is TACHI MEI or a date (if KATANA). More and better photos would certainly help.

After close inspection, I believe the blade is dated Eikyo, (永享) or beginning in 1429. 

I went down the list of Nengo, and the character I can really make out is 

永.
