  <dc:title>Photographs of scale model of VLSII, a new interferometer </dc:title>
  <dc:description>Two monochrome and two colour photographs of a scale model of an instrument to succeed the NSII. The proposed intensity interferometer featured four coelostats running on straight tracks, with a central building to house the coelostats. 

Unlike this successor model, the NSII had used two concave reflectors running on a circular track. The proposed new instrument would have been about 80 times more sensitive than the NSII. It was never built.</dc:description>
