OK so this gets done before the 25th, with the family arriving from Texas tomorrow, and as I'm running out of clues, the type I'm looking for was built by a company founded by a very famous aviation pioneer from another continent.
Sold out to a company from another country, for a relatively short period, and then sold to a company in its homeland which had bought other aerospace companies, the design in question and a number of others, though none were in production, were sold some years ago by the new owners, with just one transport type from the portfolio retained and still in production.
