Work In Progress Posted March 4, 2020 Share Posted March 4, 2020 Some context would be useful. What do you think it is about? What is the issuing authority? What if any type of aircraft or operation are you talking about? Link to comment Share on other sites More sharing options...
Mark Harmsworth Posted March 4, 2020 Share Posted March 4, 2020 If you are referring to the project to build a pipeline under the channel to support the D-day invasion then the HAIS type of pipe is from: Mr Hartley the inventor, Anglo/Iranian his employer, and Siemen the designers & manufactures See: https://www.combinedops.com/pluto.htm Or it could be something completely different given that this forum is for aircraft topics (???)

William Marshall Posted March 5, 2020 Author Share Posted March 5, 2020 No, these are Paint or Dope colours for aircraft, the order was possibly issued by the Air Ministry c. 1935. I have a number of references from paint manufacturers to this order referring to colour schemes. No specific aircraft mentioned, possibly only the colours that had to be used. Any help would be appreciated. Link to comment Share on other sites More sharing options...
