hi john
if memory serves me correctly then the t16 does have double springs on the rear and single on the front.
the t16 suffered with rearing back when on a slope which resulted in less track on the ground and so less traction, a problem that never really got fixed despite the use of double springs, although I have seen a pic of 2 t16's doing ramp climbing trials one with normal setup and one with the rear bogie reversed and the modified set up was much better but was not adopted as far as I know.
