If the Experimental Car with chassis number #37EX is compared
to #3BU6 even at a quick glance similarities are obvious; certain
details are almost identical. It isn’t too much of a risk to say that
#3BU6 is a variant up-graded by a more spacious boot and a remarkably
high degree of luxury. That can be concluded from the chrome waist band
(beneath the side windows) and from the bonnet sporting manually
adjustable air-flaps instead of simple louvres. Delicately executed rear
quarter lights are worth a note and, of course, that bumpers were fitted
front and rear.
Any purist complains that a mascot in Gold was an exaggeration as
regards luxury would be entirely incorrect though. When in 1920 in Paris
a competition had been held to select the most attractive mascot in the
world, the British motor car manufacturer had entered their Spirit of
Ecstasy. One made in gold and that one had been awarded the 1st Prize.
Henceforth it remained standard at Rolls-Royce to offer "ex factory" the
mascot in Gold as an alternative - and to charge a significant extra
amount on such luxury.
