Swordfish floats, looks like a Hector/Hind tail and Walrus Pod with what looks like a collector ring but I think is a circular guard/mount in front of the cylinder heads?
The cabin is exceptionally beautiful, it looks like a ducktailed launch that has altered? Any Marine architects on here able to shed some extra light? I am imagining that it was mahogany or something similarly heavy, given that the notes say it was only capable of 15 knots with an engine giving 600hp?
