Restoring a Sunbeam Venezia can be a fairly straightforward operation, particularly as far as the technical aspects are concerned. Being built on a Humber Sceptre chassis / floor pan and equipped with the 1592cc engine used in many Rootes vehicles, rebuilding the engine or the drive train should be an overseeable exercise. Many parts were used throughout the Rootes vehicle range, some parts are being re-manufactured. The Rootes Manual WSM.134 is a great help in the workshop. Try your luck and find a copy on eBay.
The construction of the Venezia according to the Superleggera principle, however, may create some challenges when restoring. Rootes UK sent floor pans and engines/drive trains to the Carrozzeria Touring Nova Milanese factory, which in turn constructed a frame made of molybdenum steel on top of the floor pan. This frame already had the outlines of the body shape. As a next step, the frame was covered with aluminium sheeting which was 'loosely' fixed to the frame by means of a very small number of brackets and 8mm bolts. In most places however, the aluminium skin was merely just folded around the frame/floor pan.
Whenever aluminium and steel are combined into one vehicle, there is a severe risk of one metal corroding preferentially to the other when both of them are in electrical contact and subject to an electrolyte. In an attempt to prevent rattling of the two components and to insulate the aluminium from the steel, Touring have separated the two by means of a layer of grey felt (3 to 4 mm). This felt, however, will absorb any humidity and will thus act as an electrolyte. Just driving will generate a minimal amount of electricity through friction. According to science, the aluminium will usually be 'eaten' by the steel. Many Venezia restoration projects however, show a fully intact body and a rather 'crispy' floor pan/frame.....
For those who are not too fanatic about originality, a cure to this problem is to remove the felt wherever possible, and to replace it by a suitable black filler/glue, such as Bostik Simson ISR 70-03, which is a multipurpose elastic adhesive/sealant. Make sure to retain the distance between steel and aluminium.
The sound deadening material which Touring used all-over, the white extruded polystyrene, has become brittle over the years and turns out to be unable to withstand pressure. This material can be replaced by DOW Styrofoam of the correct thickness (slide show 3190114), or, if you prefer more flexibility, by black closed-cell rubber of the correct density (slide show 3190016).
Most Venezias are suffering from deteriorated rubber seals of the door quarter lights (referred to as 'draughtless ventilators' in the Sunbeam Venezia Parts List). Lack of a suitable master in good order prohibited the re-manufacture of this seal. As an alternative, Robert Jaarsma (USA) has had the appropriate profiles reproduced and offers those at cost, inclusive of comprehensive instructions (download here).

The rubber seal of the rear quarterlight (Plate ref. J.26 Section YS of the Sunbeam Venezia Parts List) has gone in many cases, too. Even though it seems a standard U-shape, it appeared difficult to obtain as a regular trade article. It was re-manufactured in the correct size and shape.
A few sets are available at cost from Hans Visser, Rotterdam, the Netherlands.

Some restorers may be facing trouble with the cylinder of the door lock (LH only). If yours looks like this,
you're in for a search expedition..... As you will note, the zinc alloy of the cylinder has disintegrated and the cylinder fell into pieces. The door handle itself was also used on some other Touring designed cars, such as the Maserati 3500 Coupe GT, the Maserati 4000 and on other Italian thoroughbreds like the Ferrari 250 GT and Alfa Romeo Giulietta TI Berlina 1964. So the complete door handle of those cars will fit the Venezia, but beware: the cylinders are not interchangeable! So if you face this challenge, always go for a complete door handle (with keys.....)

Robert Jaarsma and Hans Visser (and Francisco Javier Barrao -3190189- for those speaking Spanish) will be pleased to share their knowledge with anyone planning or already working on a Sunbeam Venezia restoration.
