Why wouldn’t two British owned countries have forms that are the same or very similar?
Australia still was influenced by the British in 1986, Kenya declares independence in 1964.
If there were “stock” British forms would a new country, with very few financial resources, go through the process of developing a brand new form or would they take existing forms and change the information?
It isn’t like they had desktop publishing in 193.
These aren’t similar. They’re identical.
Same form number. Same price. Same last name for the Registrar and District Registrar. Same book. Same page.
It's quite conceivable that there was some sort of British gov't specification for the layout of such forms throughout the Empire. But the odds of the District Registar and Registrar in Australia and in Kenya both being Miller and Lavender and furthermore refer to the same Book no. and Page no. must be astronomical. There is no doubt that one of these is fake, fake, fake.
If I had to choose, I'd tend to suspect the Kenya one is fake. The absence of a printer's name at the bottom edge of the form as compared to the Australian form makes me supicious.
