Hello!

I posted some photos and this is what chatgpt told me. Would like to hear your opinions. Will take some better pictures tomorow in the daylight. the lamps about gave it a bit of different look.

Thanks!

 In some cases a Fuyuhiro attribution was or is a safe call when shinsa cannot make a more definitive determination on just who or what tradition or school or smith made this sword. Often because the polish on the sword does not or did not provide or bring out the specific detail necessary. That may or may not be the case here.  At the very least, it suggests (to me) that this sword needs more careful study by trained eyes before accepting this Fuyuhiro call.

The correct kanji for this Fuyuhiro should be 冬広(or 廣).
