Two kanji mei unreadable.

[Hector]

Hi, 

 

This is a two character signature on a tsuba I'm considering buying.

The seller has no idea and I can't make it out at all as it's so worn. 😳

Any ideas very gratefully received!

 

Best,

Hector

Hi! The first character is 紀/Ki, but I'm not sure what the second one is (it's not 内, maybe something with a 釒 on the left), and I can't do any guesswork because I know nothing about Tosogu

Hi Hector, you are absolutely sure there is no sign of another kanji anywhere?

Hi Piers, 

 

That's all I was given. Does it look incomplete to you?

Hmmm... normally you might expect two kanji to follow 紀

I think I understand the confusion now.
Following the lead given me by Joe @YourBabyBjornBorg I found that this is usually the first kanji of a three character signature for the Myochin school.
