Missing one character on nengo (Shigetsugu, pics added)

[SwordGuyJoe]

This is embarrassing and I'm sorry to ask here, but can someone help me with the year?

 

I have tai-sho-XX-nen-go-gatsu-hi

Hi,

 

I do not think that you cannot read as 四 (4).

Of course i know , it is not desirable that this character(四) is carved on the tang.

Taisho Yonnen gogatsu hi.

 

You do not need to use the other form.

A rare date Joe - you really should share the rest of it if you have the chance...

Mei:

 

Boshi:

 

Hataraki (Tough to capture, but look to the right of the flash to see what is present throughout):

 

Sugata:

 

Better view of the hamon (subtile choji based in suguha):

 

Shibata papers:

 

Edit:

 

Activity in the ji (look to the right of the flash again):

Nice!

and a terrific example of why one should be a collector of Kasama...
