Some Anchor friends love the NS; most do not. Within a year of changing to the NS, the company was selling sets of the older arch stones as a substitute and had reintroduced the GK-NF series of sets. Although the NS was sold in the USA, the sets were not included in any American catalog, and the supplement sets were all GK-NF.
The NS "a-arch" design is clearly seen in this picture.
