Thank you. I haven't seen those sites yet looks like a bunch of great information. Ill definitely read through that later after work
AOI dated it to mid/late Muromachi, can't remember which one but was unsure of Mei but had some ideas tho. One of the Sukesada smiths possibly. Well let's just say Sada for now haha but the more I look at the Mei the more it looks like it might be referring to a date? Doesn't really look like a "Sada" character to me in pics but then again I'm a rookie so what do I know
Here's another couple pics
