2-seater sports, family 3/4 -seater.
Same Hotchkiss-based big aircooled twin (it went into some big bikes, too) in a rare four-wheeler derivative, its dead back axle riding on double quarter-elliptic springs. Also (like the Twin three-wheeler and T9) sold as a van. Front end as for three-wheelers, with dummy honeycomb 'radiator', interchangeable wheels, and 8ins brake drums. Good club coverage for all fwd BSAs.
