Hi Lloyd! Splendid model, are you the builder? If so, perhaps you could supply a few more details, such as scale, materials used, etc. You evidently have some connection to the SAN with all your recent submissions?
Materials Plastic card and Evergreen plastic sections. As to the scale I have built a number of models since I built this one which is now in the Naval Museum, I would have to get the drawings out to know the exact scale. I am a retired W.O.1.
