DeHavilland Mosquito RCAF

Just bought a DeHavilland Mosquito B MK lV kit from Hasegawa. The MK Vll is based on the MK lV so I will modify this kit to make a B MK Vll (Canada only). Is there anybody who know the differences between those two aircrafts ? I know that the Vll uses a Merlin 31 instead of the Merlin 21 and that the exhaust is different but what else? Is the color scheme of the RCAF aircraft the same as the RAF ? I think so, but am I right? Thanks folks! Paul
