In your link, I hate to ask one question:
The mother’s birth date : 11/29/1942
Only in the USA date format where the month is written first.
If authentic, it should have been written: 29/11/1942
How in the world would this be authentic?
The other dates below, the supervisor signed a day (USA) or a month (European) BEFORE the doctor!
I hope I’m wrong, somehow.
Also troublesome, the weight and length would be in metric.
The mother's date of birth as 11/29/42 may have been written down as she told them, or copied from ID she presented, written in the US format.
The attending doctor signed on 8/8/1961
The Supervisor of Obstetrics signed one day before the doctor, and used the US format.
Maybe...maybe he was educated in the US? Lots of maybe's.
