K150.  Iron tsuba signed Choshu Hagi Ju Nyudo Tomoyuki (the final Kanji, yuki, has been smooshed by mounting; I get this character from the former owner’s tag).  7.3 x 7.9 x .4 cm.  The nakago hitsu-ana is .7 x 2.6 cm.  This tsuba is so cool!  Perfectly crisp carving shows 2 large ships and a small boat with 3 sailors on the front and another small boat with passengers below a mountain on the back.  The fret work surround on both sides is an added bonus.  Condition is, once again, excellent.  $395.
