New Type-name Wanted
gOME public-service-vehicle enthusiasts have been
considerably put out by the new airline coach fcir British European Airways, with bodywork by Park Royal Vehicles, Ltd. Unfortunately it does not fit into any of the accepted p.s.v. categories.
One correspondent, referring to the. suggestion that the vehicle looked like a combination of the lower half of a single-decker with the upper half of a double-decker, asks: "What is the lower half of a single-decker? I suggest that if the centre gangway is moved down a bit higher, as in the bottom half of a half-decker, then you would have more floor space in the middle half of the two! " Another suggestion, based on the fact that neither of the two rows of seats runs the entire length of the vehicle, is that it be called a double-half-decker. The debate continues.

Spraying Metal on Wood
ANOVEL idea in connection with the employment of wood as an alternative to scarcer materials is to spray the surfaces with metal. Even the first coat gives a smooth covering which acts as a seal against 'moisture and helps to prevent decay. Normal spraying technique is employed and the deposit on the wood is a dense coating of a fine texture, containing little oxide.
Woods most suitable for this treatment are said to be cypress, birch, gum, mahogany, oak, redwood and walnut. Resinous woods can be treated but tend to sweat at high temperatures. Each coat should be left for 15 minutes and the final can have a light lacquer seal. Wet-sanding, smoothing with a rubbing compound and polishing will give a good finish. This treatment might overcome some of the difficulties experienced in tropical ,climates.
Not Drinking Water
RTRINGENT requirements laid down by overseas purchasers of British vehicles have conferred benefits on home as well as overseas users. This has been seen many times in the past few years. One of the latest manifestations of this close study of buyers' needs is seen in the use by bodybuilders of highpressure water sprays which effectively test the water-excluding properties of finished bodies.
One of the first outfits was used by Leyland Motors, Ltd., for testing its singleand double-deck bodies. Duple Motor Bodies, Ltd., recently demonstrated its own unit. After a concentrated assault on a body from a battery of water jets, one member of the party remarked that all that was needed was a large fan blowing a 50-m.p.h. gale, to make one feel like a day tripper.
Rather a different method is employed by Park Royal Vehicles, Ltd., where water jets are reinforced by air pressure. In this case the test is carried out with the vehicle in primer paint, so that the possi bility of discovering leaks and their cause is increased.
At the Duple works, on the other hand, the vehicle is run over rough ground between tests to ensure that body strains developed in service do not result in. leaks at any point.
S.P.D. Enterprise for Safety
IN the interests of accident prevention, S.P.D. Ltd., I 3/5 Salisbury Square, London, E.C.4, has prepared an interesting and striking booklet, a copy of which, together with one of the Highway Code, is being distributed to each of its drivers.
Opening with general statistics on accidents, data of those in which the 575 S.P.D. drivers were con=, cerned last year follow, and it is mentioned that the company spends £8,500 annually on accident repairs and replacement hire. Subsequent pages give 18 plans depicting accidents and details of how they can happen. It is a worthwhile publication in a worthy cause.
