Sports saloon, various customs.
Basically an up-engined 31/2-litre with the same chassis specifications, servo brakes (of course), twin coils usually where Speed 25s have coil and magneto ignition, and the usual up-market Alvis specification. Some lovely dropheads, though these not catalogued. A genuine 100mph, but watch it, there's a 12mpg thirst as well.
