Lanchester LD10 1946- 1951

The LD10 was one of the smallest vehicles to be built by the Lanchester Motor Company (under Daimler ownership). It was first conceived before the war and production would have gone ahead if the restrictions on steel had not prevented the chassis manufacturers (Briggs Motor Bodies) from supplying the chassis that were needed for vehicle build. The car was designed with a "modern" vee-shaped grille and would have been well ahead of its time if the war had not halted its production.

History. Darren Watkinson

The 1939 prototype car still exists and is very interesting, because all the wing pressings are shaped to take the vee-shaped grille but have been disguised and adapted to carry the traditional flat, pre-war grille, presumably to prevent competition from seeing the new design. 95% of the first 2,426 chassis (1946 to 1949) were fitted with saloon bodies built by Briggs Motor Bodies Ltd. of Dagenham and 95% of the last 579 chassis (1950 and 1951) were fitted with coach-built bodies built by Barker and Co, at the Radford Works, Coventry. The remaining 5% (or so) were fitted with a range of interesting bodies, including several vans, several two-door drophead tourers and several saloon car bodies built by other coachbuilders. Other known coachbuilders include Avon, Hooper and Wentworth.

2020 proto.jpg

The well-mannered small car of high quality, the Lanchester Ten, appeared for 1950 with a new four-door four-light coach-built saloon by Barker.  The mechanical design of the chassis has not been altered; however, the appearance is both modern and attractive. Beneath the prepossessing exterior there is an interesting construction, for the body is a strong composite structure of steel, timber framework, light alloy centre pillars, and aluminium alloy panelling for roof, doors, boot, and lid. This construction should also save weight. At the back is a capacious luggage locker, the lid of which opens upwards to give access to the compartment and to the spare wheel locker beneath it.

The interior accommodation of the new saloon provides two bucket front seats, both independently adjustable for leg reach, whilst the driving seat has a vertical adjustment as well. The wide rear seat has a folding centre armrest and elbow-rests at the side.

The drop windows of the four doors, which are hinged to the centre pillars, are of curved Triplex glass to reduce the thickness of the doors and so allow extra width in the body at waist-line height.  To economize weight and increase rigidity the windscreen is fixed, and a sliding roof is not incorporated. The equipment is thorough and includes such items as pockets in all doors, a large glove box with a private lock.  The instrument panel and the cappings are carried out in polished walnut instead of painted metal as in the Briggs.  To conform with overseas regulations the number plate is not inbuilt but bolted on and provided with separate illumination. There are oblong rear lights in the tails of the wings. One small change was made to the compression ratio being reduced from 7.6 to 7 to 1 for low-octane fuel.
