Kitbag
I apologise for the rudeness and tone in my post of the 9th - please note the time, and the fact that I had just returned from a well-known re-union in London! I completely mis-read your message and, given my desk-appointments in the mid-80s, probably bridled at your 'appalling spares shortages etc' comment.
Jacko has since (IMHO) put things in the historically correct perspective.
Sorry!
