I was chatting with an antiques shop owner in Lilydale (Tas) yesterday. Boats came up in the conversation (as they do) and he showed me an emblem mounted on an elastic band. He didn't know what it was or the nationality, and I thought some of you ex navy guys may have some idea. Btw the item above it is a ships ink well, the ink receptical is ceramic, the holes around the circumference are for the nibs/quills he thought.
He also had a set of Ian Nicholson's "Log of Logs" that may be of interest to someone.
