The technical term for individually built it is handmade
strange about the comments on the individuality of the Tucano when the wing attachments on the Grimrod could be inches out from each other.
Incidentally you should see some of the bigger Cessna twins, farmers in Witchita would farm during the summer and build aircraft during the winter and it showed, you dreaded getting new skins pre drilled because nothing would ever match, they were built in three sections, front, middle and aft and then riveted together with rivets through rivets, figure of eight rivets and I even saw three rivets all joined up and overlapping in a row.
The Ex RAF Tucano sells well in the USA with a decent Nav fit in it.
