Charles, you posted a very interesting question which, hopefully, you have been able to find the answer to. However, as this area of camouflage and markings can be quite confusing, especially to those, including modellers, who are 'new' to the subject, I had thought of doing a set of simple charts, illustrating these codes, bands, bars and colours, in order to try and clarify at least part of the sometimes puzzling displays of LW markings. The reasoning behind the proposed project being to provide an 'at a glance' reference for those without access to more complete, and/or expensive reference works. If anyone thinks this might be useful, I'll get started on it, but it might take some time, as the 'system' became a little more complex as the war progressed.
Terry.
