Thank you Jean,
Yes, the background does help.
Please excuse the photos in landscape rather than portrait orientation.
The blade is so out of polish that I am unable to identify the hamon, I know this would have been helpful in identifying the smith.
The hada is best seen with a jewelers eyepiece and appears to be a very tight, straight grain.
The blade, saya and kogatana came together when I bought them a couple of years ago.
I made the tsuka as a temporary fix.
Hopefully this sheds a little more light on the subject
Many thanks
Richard
