)For the Cork Small Boats Festival over the last number of years we have been using: www.druidcraft.com . They make a simple bronze mounted "Cork Crest" (much sought after I may add).
They are based in Ballincollig, Co. Cork where they manufacture all the various pieces. Some of their pieces are incredible and are works of art (they do army shooting trophies that are stunning). They are surprisingly inexpensive.
They have a website but it is worth giving them a call as not everything is listed there.
