I was just sent an email by a very observant member, about the first picture above having a 3 bladed prop and I immediately also noticed the 1400 series paint scheme.
I can't remember why I thought the yellow Helio on floats was 2510 C-GIDG since the registry is so small and the only thing you can make out is the C- part of the registry. But comparing other pictures of yellow and green Helios with 1400 series paint scheme and a Canadian registry I came to the conclusion the picture is
probably c/n 1229 C-FMQU with a similar yellow and green 1400 series paint scheme or
possibly c/n 1401 C-GHDT or another Canadian 1400 series Canadian H-295 Helio C-GIUW c/n 1427 that I don't have a picture of.
Unfortunately I cant remove the picture and move it to c/n 1229 but I believe I will put a copy there.
