My goodness - you all make it sound like these things are rare in UK skies! Apart from the historic flight one, we have another SIX based, one more due, and potentially more coming...
There are two N reg Alouette IIs, one at Redhill and another in the Barton area - plus an HA reg one near Leeds. Not forgetting three G- reg ones - one in Swiss markings which often appears at Helidays and two others currently not flying (one on maintenance at Droitwich and G-UGLY which has an expired CofA and may be at Gamlingay?).
Then, there have been various Alouette IIs auctioned recently, including one which went to Hungary for refurb before coming back here to be based, plus potentially another four others ex-auction.
And I'm assuming we're talking about an Alouette II, as it only says "Alouette" and there's a G reg Allouette III around now too, isn't there md600driver?....
