Thank you both for your responses, I have dealt with Mr Holcombe many times over the years, I plan a trip to his museum in the near future. The account of bending the iron to fit the curves of the ship makes me wonder if some sections were bolted on horizontally rather than the familiar vertically. I have confirmed the front ant back were done vertically. Any opiniona and suggestions would be greatly appreciated. Thank you again. Sincerely, James Holloway
