In that case Sooty, I'll go with you on that one.
Obviously, being of younger years, I don't have any first hand knowledge of the situation at the time, and can only go on the references I have. I'm more than happy to be corrected by people such as yourself who have first hand experience of the matter. I have see much of the promotional material being trumpeted of RR and the 593, and have also spoken to former RR employees who obviously trumped up RR's involvement with the 593 and more pertinently the 22R, which in all honesty I was a little confused about myself. Thank you for clearing those issues up.
