What's not to like about a screw? ;).
Newfoundland (note the capitalized "N", are big friendly beasts but the darned things are about the size of a Shetland Pony and I would hate to have to feed one. Also, 1982 was still a bit too close to the adoption of the red maple leaf flag. I know even my dad, a WWII vet, swore that his flag was the Canadian Ensign (small Union Jack on a red field with the Canadian Coat of Arms in the corner) 'cause that was the flag he served and fought over. So I imagine that in 1982 there were still a lot of vets and others to whom the red maple leaf was too new, too different or whatever.
But a Robertson Screw! It doesn't get any better than that!
