JFC Fuller - Thanks!
Now that is a very interesting article and find - I thought I was pretty up to date on our various developments and prototypes, however I did not know about this one at all!

One can only wonder as to what came of it - we have done joint development with the Germans before (more recently on joint radio development), so any further info on this project would be most welcome. I can only assume though that it did not progress much further due to lack of funding on our part/and or lack of political will on our part...?
Once again, thanks very much for this insight!
