When Paraparaumu resident Paul Harrison, aviation historian and author visited his elderly aunties at their rest home recently, he was presented with an item of family memorabilia dating back over 100 years.
His aunty Mary, 95, passed over a small monocular which Paul immediately identified as a military spotting scope.
A monocular is similar to a binocular used to magnify objects in the distance.
The difference is monoculars produce two-dimensional images, while binoculars add perception of depth, a third dimension.
