Blade signature and date, need help

[EdWolf]

I believe the signature reads Bishu Osafune Sukesada but I'm not sure about it. The signature is hard to read. The date is also difficult but it looks from the Taiei (1521) era. Am I right? Feel free to comment. Al help will be highly appreciated.

Ed,

Check the entire nengo list for the 1500s

Possible Ed!

Even though I guess the nengo starts with “天”. We need better light to make it safe. Try oblique light!

Peter, do you mean Tenmon?

Uwe, I shall try to make a better picture soon.

Ed,

You are right. It looks like a Tenmon (yes yes "Temmon') date and I bet you it is a 6th year so that would make it something like 1537. And, to be sure better images would help. But I actually think you should have GUESSED this basic informaton the instant you saw this nakago. It absolutely looks like a a late Muromachi era kazuuchi mono. Osafune was really and truly cranking out swords at that time and the great bulk look just like this. Look at the size and shape of the nakago. Consider that rather nice old rust. What it "says" only confirms how it "looks."

 IMHO
