A good job PMM
Yes the venerable old Mosquito is a decent kit and builds pretty well considering its age. I did the FB Mk.VI nearly 2 years ago and really enjoyed the build.
But yes it needs improvement but I dont think its in Airfixs plans to add new parts such as the canopy or parts for a bomber version. I know Humbrol in the late 1990's tried to upgrade kits by adding 'modern weapon sets' to kits such as the Jaguar, Harrier and Buccaneer, but did it really work? No I think the Mossie needs the new tool treatment and has been on my wishlist for a while
