Oerlikon query

[SG500]

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.

Bob Gerber probably knows - he's the Oerlikon ammo expert.

Any thoughts Bob? :tinysmile_grin_t:

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.

Does anybody know if this book is available for free on the internet?

I think you need to check Ebay from time to time. Have seen one on offer last year.

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.
