Of course off-test on 23 november 1934 would al ost cetainy mean that it would be months later before the body was on the chassis. For the guarantee, the car would need to be inspected by a Rolls-Royce inspector first, before delivery. In foreign countries or with unknown coachbuilders this could cost quite a bit of time, as someone would need to travel down: with Spain, it would be from France. For this reason some cars were supplied without guarantee...(customer got impatient). In Rolls-Royce folklore the build date is the determining factor, so it would be considered a 1934...Thanks for the point.
