This is how the Canadian Army introduced a new camouflage pattern for all vehicles in use.  Notice the time lag between the introduction of the scheme and the date of the 5th Divisional Orders.  This is not unusual.  As well, there may have been vehicles  issued in the new scheme before it was made official in November 1941.  Note again, the instructions to use the alternative paints till stocks of them were exhausted.

At some point, SCC No.7 Dark Green came into use as an alternative to SCC No.2 Brown.  SCC 7 was authorized for use as dark disruptive pattern over vehicles painted SCC 5 "Light Mud" in Italy but photographic evidence shows it in use in the UK with MTP 46 patterns.  Written evidence of this has yet to be unearthed.
