It is very clear that all their models are cast based on one set of CAD drawings regardless of scale. That is, if they did ND in 350 scale, then all their ND models are made based upon that. In the case of ND, I am convinced that the 1250 model was based upon CAD for 350, because unlike their other kits, this one has numerous small bits that could have been cast on the hull and deck such as anchors, anchor chains, paravanes, and hose reels, things which would likely have been done separately in 350, but never in 1250. Many parts are so small and teeny that they can't be used, break or disintegrate when cutting off sprues, or disappear into another dimension. As a result, some scratch building is necessary. I expect that in 700 or 350, this is not as much of a problem.
Nevertheless, the detail is superb. But building these, at least in 1250 scale is a challenge and not recommended except for skilled modelers.
