I bet someone with skills to paint could paint that engine to look like iron .     | ||

| Registered Member #105 Joined: Wed Jul 15 2009, 12:01pmPosts: 3560 | now go back and compare this image with a level waterline the boiler is now level so is the cabin and the floor at the stern but the floor at the bow is now slanted as well as the wheelhouse and smoke stack. the question still is are the frames built to a level waterline or keel? who has the answers? well I contact the oldest shipyard in Nova Scotia still in business since 1879 to see if they were willing to answer questions.  | ||
