Hi Richard,
I started to build "Westward Ho" from the Practical Mechanics drawings, but I was told that these were not very close to true scale, so I switched to a set of drawings provided by a Campbell enthusiast. The model pictured in the PM articles was not built to the drawings in those same articles.
Mine is now nearly finished, but scale draft and heavy superstructure probably means it would'nt be much good on the water. Still, it looks good. I have the Collard books, so if if you want help with detail contact me.
Malcolm.
