coley,
I must apologise for the duff steer ref Wallop colours - mea culpa - Wallop 212s are indeed cam / orange. What can I say other than I am clearly starting to take after my name sake and the senility is more advanced and eyesight worse than anyone might have first thought - the next medical should be interesting. Still I don't think I have quite reached the state of my first instructor who had cataracts!
If nothing else an example to the youngsters against taking the confident statements of an old fart at face value. In fact, I would postulate it as Melchett's Law: the accuracy of any statement is inversely proportionate to the confidence with which it was first delivered.
Now then Nurse, where am I and why does it all smell of biscuits round here?
