Hello Martin,
The model is printed by Marcle now if there still doing it, 184 A3 sheets of card that cost £300. it was first designed by Captain G. B. Robinson, Lieutenant Commander R.D. Royal Naval Reserve. long before CAD, like some one said it's like building the real ship but in card and not steel, lots of cutting out and thousands of 1mm slits to cut into each peace, as I have said before not a weekend build. Am building it as my late father-in-law was a plater in the Austin and Pickersgill ship yard in Sunderland that build most of them it should be build as a display model but you will have seen am going to make as a RC model so will be altered in many ways a member on here called Carl with his father build one a years ago as I have done over the last week running 3/4 inch Ali square tube down each side of the hull most of the way on top of the plywood hold floors glued on top of the card tank tops so it will not break its back the reason being I will need three/four battery's plus some where near 120lb of lead ballast to get her any where near the water line I have made 20, 4lb ingots so far with a screw eye in each so I can lift them in and out when at pond side I hope to explain ever thing as the build go's on.
Regards Howard.
