I thought it was the Seagull one too.
Then the Black Horse (which turns out to be the Seagull by another name) - but thanks Ray.
But in the end it turns out to be the Thunder Tiger version from Amerang actually from Xinggyang province.
Ken Coper is on the trail right now - but if it's not available anymore then it's Isopon time.
There are so many makes, colours and different size versions of this plane - well it could make you GASP.
