The Isis announced in July 1929[3] was a revised version of the 1927 Morris Six JA series and used the same 2468 cc engine and 3-speed gearbox.
Following the court-forced separation of William Morris from his joint venture with Edward G Budd the all-steel body was replaced by a traditional wood-frame construction.
[1] A de-luxe version, the Morris Twenty-Five was launched 12 October 1932 for the 1932 London Motor Show with larger 3485 cc engine.
The car was based on the four-cylinder Morris Oxford Series II, sharing its almost-unibody shell and torsion bar front suspension.
The wheelbase and front end were lengthened to accept the larger straight-six engine, and a "woody" 2-door estate version was also available.
Unlike its sister car, the Austin Westminster, which enjoyed moderate success against the volume-selling Ford and Vauxhall sixes of the time, sales were poor, with only 8,500 sold.
The manual version had a four-speed box operated by a short gearstick on the right-hand side of the front bench seat.
