Thanks Doug

That sheds a lot of light on the subject.
Chief of Defence Staff, NAV CANADA and the Department of Natural Resources Canada all show the name as "DeHavilland" one word and this is how the new book shows it "deHavilland" in Canada.
That is what brought forth my Question or Post.
Also I have an old old tie which was left to me. It is manufactured by PEGASUS CANADA and is the same width as a Military tie. It is brown in color and has pictures of one aircraft on both sides with a capital D on the port wing and a capital H on the starboard wing.
I believe the aeroplane represents the Comet but not sure. Across the rear fuselage between the wing and the rear stabilizer is the name CANADA. The "D", "H" and "CANADA" are done in gold. The Aeroplanes are flying up the tie front and back.
It looks very well made.
I will probably donate it to the museum but will keep it for a while yet.
Thanks for all your help

Cheers...Happy Landings...Doug
