Oops . . . TChad is right. Some typewriters did provide the number 1 (one).
This image shows one of those keyboards:

But . . . if such a typewriter was regularly used for those Australian registration certifications, why was the ‘1’ not used throughout the document? Was the typist a fill-in, a pinch-hitter for the day?
Oh ye of little faith.

Maybe just habit. When someone learned to type on a typewriter without a "1," hitting the lower case L became second nature. So when that typist started using a typewriter with a "1," he would often forget to use it. At least I did. The lower case L still did the job.
Close enough for government work.
