Hi Hal , thanks for the extra photos . Are you thinking of doing anything with the blade to try and stem the deteriation ?
We are the Pilgrims , master, we shall go
Always a little further : it may be
Beyond that last blue mountain barred with snow
Across that angry or that glimmering sea...
Hi Hal, I'm not sure what you paid . But this blade might be worth a new polish if it has not been in a fire or damaged The saya is post Edo .Tsuba looks Goto late Edo unfortunately in bad condition. But with a cloth and Clove oil this may come up OK and the rust maybe lifted .The Seppa has left corrosion marks which means it hasn't been separated for a while that's a good sign of age .Fittings are all around the end of the Edo period and matching to.Very nice restore project as long as the blade meets Japanese criteria for evaluation.Mei , I will not go into this here ,as I am not confident to comment without seeing it in my hand. Tang looks OK from your picture.
The fittings are definitely Edo Period.
LIFE'S LOSERS NEVER LEARN FROM THE ERROR OF THEIR WAYS.
Thanks Bob, are the fittings showing up as copper or brass on your computer screen.I only have a small older lap top.
Cheer's , Mark
