As far as I'm aware, there was never a 340 GLT in any market. Another '340 GLT' has been conconted by a member in London, using the bits from a 360 GLT. The highest trim level I'm aware of 340s coming with was GLE spec.
Europe generally had lower spec cars than us, so I doubt this was a factory effort. I suspect someone 'borrowed' a "T" badge and some glue....plus the colour coded bumpers from a 360!
cheers
