28+14 was also the pre-Berne term in Canada and Newfoundland, and in
the pre-Confederation Province of Canada.
At one point during the late pre-Confederation period (1840s? 1850s?),
at least Nova Scotia and Prince Edward Island also had n+14 terms,
although their initial terms were 21 years, not 28.
I'd suspect you'd find a similar history throughout the Commonwealth
jurisdictions. Anyone have info on early Australian, NZ, or RSA terms?
