Here is a large katana I own, signed as you see. Any ideas on the mei would be welcome. My initial thought was Heianjo Ju Masatoshi based SOLELY on the last kanji you can just make out that is large compared to the rest. Very large hamon as well.   Thank you for your input in advance for my research.  Nagasa is 68.5 and has a large machi okuri done to it (cruddy last picture)
