Katana signature identification

Greetings, I'm a new member.

I am new to the study of Nihonto, but acquired this blade and am enjoying learning about it. It is about half an inch over the minimum length for a katana and relatively heavy.

I found it interesting that the habaki is of 2-piece construction, gilded, and contains a mon. Fits well, seemingly original(?)

Secondly, the tang is inscribed on both sides. After a colleague translated the signature, I found it in the database as Tamba No Kami Fujiwara Terukado. The signature appears to match that in the Club archives (http://nihontoclub.com/smiths/TER16); does this seem valid? Also, we were unable to figure out the inscription on the reverse. Any assistance would be much appreciated.

Thanks!

Have a look here.

That's very helpful,

That's very helpful, thanks.
Is this Yoshisada in the database? I didn't see it.

Probably? Not a common name

Probably? Not a common name by the looks of it. Can't figure out the second and third characters, maybe a place name? Have a look here as well http://www.christies.com/lotfinder/lot/a-mino-katana-signed-tamba-no-kam...

Interesting

I infer from this that Terukado co-wrought at least three blades, then.
What would be the reason for this; could it be that an elder smith was
working in conjunction with his apprentices?

Kuwana

The 2nd side is "OITE KUWANA ZENJOu SAKU KORE".
The ZENJOu could also be read as Yoshisada.

Zanjou

This is consistent with the blade offered by Christies, then.
