Is there a check ball missing on the cross section of the "English" injector?
Yes there is.

Another injector book is The Model Injector, by Ted Crawford. It was published by Australian Model Engineering, but they are now out of business. I think someone else still stocks the book. It looks to be based on the English design.
Two books on prototype injectors are: Locomotive Injectors, published by Tee Publishing, and Injectors: Their Theory, Construction & Working, by W. W. F. Pullen, reprinted by Camden Miniature Steam Services. Lots of math in this one.

Hi all,
Anthony, I suspect that the book you are referring to is "Miniature Injectors Inside and Out" by DAG Brown in the UK. The book is an expanded version of a series written by Mr. Brown for "Model Engineer" magazine in the UK perhaps ten years ago.
For those interested in injectors, especially how to reliably make them, and test them, and trouble-shoot them, I can heartily recommend that book. I've now made three injectors based on the designs and construction methods in the book and they all worked first-time.
That said, Anthony's products are darned impressive, to say the least!
Best regards
Steve
