Funny then that the one that you did post from the early to mid 60s looks nothing like the "Bomford"/Australian or "Obama"/Kenyan ones.
What we need are other South Australia BCs from that period, or other Kenyan ones from the same time frame
Do you expect me to have a copy of every single type of Australian birth certificate ever issued? I think that's a bit unrealistic.
What I can do is show that there was a common format (that is what it is actually called) used for all Australian birth certificates and provide examples that show that format. A format that is evident on the Bomford certificate as well.
Let's look at this together.
The first five birth certificates in that composite are Australia (the alleged Bomford certificate is included). I think the commonality of features between all five certificates is pretty obvious personally. The last three are from elsewhere in the Commonwealth (England, Canada, Rhodesia). They are obviously different.
The alleged Bomford certificate looks like an Australian certificate. So does the alleged Kenyan certificate.
