In the shed, on a back shelf, I had a started hull for HMS DEVASTATION, started some time ago from NMM official plans, which, as they were a combination of two ships 'Devastation' and 'Thumderer', I'd called HMS Thunderation. The following photo shows progress to present, and I expect (hope) to have a water going model by spring.
The model is some 22 inches long and I'm not sure of the scale offhand. Progress is not going to be swift, but I shall keep you informed now and then.
For those interested in such things, I recommend a website www.victorianshipmodels.com/colossus especially the little video where the ship is put together piece by piece, with all the internals falling into place.
