[gutvol-d] 28+14

only from the founding of the US to ~1831, when 14 + 14 was repleaced by 28 + 14, a standard which I don't recall was ever adopted elsewhere. This "standard" was again replaced in 1909 with 28 + 28, and again in 1976 with 75 years [renewal not needed] and in 1998 with 95 years.

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?
