Number 4 Plane Type Study


Print Friendly, PDF & Email

This study has taken me many years to collect and then categorise the planes, and I still do not know whether I have things right.  This is due to the fact that there are no known catalogues of WS products  that would help to guide my judgement as to what was manufactured and in what order.   It has therefore been necessary to collect at least 30 WS number 4 planes and try to make sense of the characteristics of each plane and to try to place them in some semblance of manufactured order.  As you will hopefully appreciate, this study may be prone to future corrections, but please bear with me....      You will have to refer to the 'Analysis of Components' section on this site for more detailed references to the named characteristics of each type.

I chose the 'Base Markings' as the most probable way of categorising the planes.

Since starting this study I have discovered that many of the smaller parts show no decipherable relationship in this study, and I have therefore cut out their inclusion so as to make the end result more easily understood  by the reader (and by me too!).

 

The WS #4 planes were issued at 25cm long and 6cm wide.
