Yep it's definitely either a remarkable piece of forward
planning or a remarkable coincidence.

Decimalisation was first planned in 1849 (introduction
of the Florin) but didn't take place until 1971. I imagine
it was definitely "in the offing" by 1955, so maybe Tennent's
were anticipating everyone drinking out of half-litre glasses
and decided that 440ml would leave enough room for the
head? All guesswork really!
