In a recent thread (which I can no longer find) someone mentioned a particular blue 240 being a rare colour and being corrected that it was actually reasonably common.
One of my projects for 2019 (hopefully) is this 88 wagon in a pale ice blue with code 553 (also has an unusual build plate with different date stamping than standard. A web search reveals nothing on this code, as though it never existed. One of the Volvo Club NSW 740's is very similar.
Anyone able to shine some light on this paint code?
