Overall silver. There are plenty of pictures of it on the web I’d you Google ‘Mosquito CF-HML’ that confirm this. No idea on the fn stripe colour in that particular iteration of the Spartan Air Services Ltd scheme though.
Don’t quote me on this as I can’t remember where I got the idea from but I seem to recall that the fin stripe was red, but looking at that picture I’d say it was more likely to have been blue.
