As I'm sure you know already the Olympus was a family of engines developed
over a 20 year period.

Sure, thats true of most engines in fact


Weren't some of them also used in ships? I'm sure
also that I've seen a pic of a Vulcan with an underslung 593 under test
during the Concorde development programme. THe size difference is very
noticeable.


Quite true.
