Background information:
Payphones of model 1100 had the familiar green color as PTT Telecom carried that as a company color. Model 1100 was designed in 1984 to replace the at that time more than 50 years of officiating standard Telephone.
In 1993 and 1995 newer models phoneboxes/columns were developed, also with the familiar green color, but phonebox model 1100 has served in various places until after the year 2000. One of the reasons that pay phones could be found almost everywhere in those days, was that until 2008 the law stipulated that 1 pay phone should be available for every 5000 inhabitants.
Architectural details:
Payphone Model 1100 has four walls predominantly made of glass. The purpose of this was to prevent vandalism and to provide transparency. Vandalism remained a matter of concern, therefore there have been phones with Plexiglas walls for a while. This acrylic yellowed easy.
At the top of the cell walls was a green window with the word TELEFOON, on the sides were the words PTT Telecom. PTT Telecom (now part of KPN) managed the Telephone booths.
Note: In assembling this model precision and experience is desired. This applies in particular for the scales 1:160 and 1:220.
