Oerlikon query

The Oerlikon pocket book published in 1958 shows a black and white photograph and table listing cartridges from 35mm to 60mm with varying case lengths.
The photograph appears to show a wide selection of the rounds.
My query is....... do any of these rounds exist or are the rounds in the photo just made up dummies and the listing just a theoretical data table?
I don't know if I'm having a massive mental blank but nearly all of the rounds listed are completely unknown to me.
Dave.

PS - there is one error on the table, the one listed as 25mm should be 35mm.

I had a look at my copy Dave, and I think they are theoretical cartridges to show the large increase in case capacity required to meet a velocity increase of only 30% in any given calibre. Whether the cases were actually made or mocked up for the picture I do not know.

Thanks Tony, yes Bob got back to me by e mail, he seems a bit shy on the forum....
Its an interesting little book.
Dave.
 
ECRA members should keep an eye out for the April issue of The Cartridge Researcher - there'll be a substantial article from Bob on this subject.
