Farina drophead 401
The first series of this type was introduced in 1948, and
for two years was fabricated alongside the Type 400. First production
models were leaving the factory in 1948. A second series was introduced in
1950. The third and final series followed in 1951. Production ceased in
1953.
Bristol Type 401
The Type 401 was the second model
produced by the company. The First Series cars are easily identified by
the distinctive ridge along the lower edge of the body. Where it differs
principally from the Type 400 is in the form of construction and material
used. It is built on a form of 'Superleggera' matrix of steel tubes
mounted on the same open 'A' frame steel chassis, with different
outriggers at the rear to accommodate a lower mounting position of the
fuel tank. Unlike the Type 400 the body shell of the Type 401 is
completely aluminium. The doors also have wind-down windows and being
larger it comfortably seats five persons.
A recognition point of the Type 401 in
its original trim was that the front grille inserts were painted black
whilst the surrounds were chromed. Perhaps not knowing this, or preferring
to change the specification, some owners have opted for silver-painted
inserts, which were the style adopted for the Type 403 — or even chromed
inserts, which was the style adopted by the Factory for the Type 400.

Farina Drophead
In about 1947-8, a number of Type 400
driven chassis were sent to Stablimenti Farina in Italy, where various
design exercises were carried out.

Touring Superleggera Saloon
As with other special design exercises
being evaluated, a number of Touring Saloons were built upon early
chassis. Importantly, these were delivered during the development period
of the Type 401 Saloon.
The design was much admired, and though they were light and proven to be
fast, they were also fairly noisy. The style was patently sound since it
had appeared in many other forms, for other marques and if a little more
more upright than desired at the front, unlike other styling exercises it
was certain to influence the Bristol developed Type 401, and the later
Type 403.

Perhaps it was not surprising that the
construction favoured by styling house Touring of Milan was their patented
'super-light' or Superleggera method. This involved building a body
support matrix of wire-tied tubular or lightweight metal rod frames on
which to mount the body panels. In the detail, however, this did not meet
the high standards of construction set by the Bristol Aeroplane Company.
Nevertheless, the benefit of the weight saving achieved from this method
of construction was not lost upon the Bristol engineering design team.
Thus the Touring Superleggera method was quickly refined and
adapted to a more sophisticated if slightly more expensive level: first,
by using proper cruciform fitted joints at all junctions, instead of a
crossover of wire-tied metal rods. This formed a stronger support matrix,
on to which the body shaped skin panels could be jig mounted and then
neatly and uniformly welded together. This method distributed the forces
applied upon the outer hull much more evenly into the matrix of the body
sub-frame and into the chassis.
Another adaptation was to cover the
support matrix itself with sound-muffling material before fitting the
outer hull of the body. This, in conjunction with underfelt applied
throughout the floor pan, greatly reduced the noise levels transmitted
into the cabin. The trim cloth of the cars was replaced by quality leather
and woolcloth fabric, along with Wilton carpets for the floors. This
completed the cocooning of the passenger cabin and along with a slippery
windcheating shape, provided the desired development of the Type 401.
Beutler Saloon
This particular car, with its chassis
plated as a Type 401, is fitted with Saloon Coachwork by Gebr. Beutler AG
of Thun, Switzerland. Two such cars were created and were originally
painted in two tone fashion, one having a black Roof and White or Ivory
coloured body, and the other a white or ivory roof and black body. At
first glance, the coachwork on these two chassis was very similar, but in
some details they were slightly different. For example there are a number
of small porthole type vents set into the side of the front wings. The
other Saloon did not have these. Some years later, in 1957, a third saloon
design was to be executed by the Company, this time on a Type 406 chassis.

This
example has been resprayed. It was originally the unit painted with a
black roof and a white or ivory body. It went direct from Switzerland to
Ceylon and spent many years there, before finally being brought for the
first time to Britain. It has since been refurbished and repainted two
tone with a pale grey roof and emerald green body.
