In the middle of the 20th century the high streets of small town New Zealand were full of specialized businesses and crafts which today are only found in the main centres. Take D.A. Blackburn- a repairer of watches located on Foxton's Main Street.
Before the arrival of cheaper watches which are easier to replace than repair, there were many such craftspeople in business. However- maybe Blackburn was too specialized for a town of Foxton's size. Kete records show him in business in 1960 but not in 1955 or 1965, so his shop didn't last as long as many others who took out cinema advertising in Foxton.
Blackburn also sold watches and clocks- all tested and guaranteed!
