to clarify
I recently posted a comment on the $65k ebay rover, noting the home-market headlight trims. If you look at a UK market series II or IIa, you wil notice that the headlamps sit on a shallow bump on the radiator panel (breakfast) rather than the 1" deep chrome ring that is common on US LR's.
And the change to headlamps in the wings was simultaneous in all markets. With the usual exceptions I am sure to account for use of existing parts stock as with all those types of changes.
A Land Rover would never turn up to collect an Oscar. It'd be far too busy doing something important, somewhere, for someone."
