Katana Mei thoughts

[Ron M]

Hello here is my post on another thread about thinking this may be Heianjo Masatoshi but open to suggestions if any at all, thank you in advance

If anyone has any input I would appreciate it. Thank you

Ron,

in some cases, when corrosion has eaten away too much material, signatures remain guesswork. In this case, I also thought the first KANJI might be TAIRA, but I have no books on blades or signatures to check that. 

What you could try would be making photos on a plain dark background, in a dark room and spotlights (not too strong to avoid glare) shining from the side.

I found that extreme magnification often does not help much.

I looked at this and I too thought it was a bit of a dead end due to the corrosion, but yes Heianjō (平安城) is plausible for the first three characters. The one after that is... maybe Hiro (廣), or something else. It doesn't look like Masatoshi (正俊).

Maybe an X-ray would pick up more definition? 

[ROKUJURO]

Yes Piers,

I did not think of that. Tthe police would have the technical means for that.
