smudge,
just to add to the 'confusion' (in my head anyway) when we first got the 'K' I seem to recall the nosegear ground lock was a largish wedge shaped bit of kit. Quite what the mod was to the nosegear that resulted in the pin being substituted I know not.
There was originally a tie down scheme for the nosegear but again I cannot recall how valid it still was with the modded nosegear.
