Good morning,
perhaps this is of interest to some of you.
Last weekend, while being parked at a gas-station along the A-3 near Frankfurt, I saw a Dutch SUV passing by with a trailer, carrying a army-green Alouette II, heading north.
The Alouette carried a small dutch flag. Further no markings seen, but as I saw it when it already passed, I might have missed them.
regards,
Michel
