The Delta range of commercials was introduced in November 1933. Smaller than the Beta, which was launched at the same time, the two-axle chassis was rated at three to four tons capacity. Both lorry and bus chassis were offered in normal and, from mid 1934, forward control types and a single example of a coach was also made. A tractor version for articulated vehicles was exhibited at the 1935 Commercial Motor Show but seems to have not gone into production.
The 20/60 3705cc 4 cylinder petrol engine was used with the VS4 diesel as an alternative from late 1935.
Chassis numbers were in the 963xx range for the petrol engine and 965xx for the diesel chassis.
The number made is not known and there are no known survivors.
CHASSIS
The chassis cost £425.
BODY STYLES

The normal control Delta tractor unit with Crossley cab. It was designed for a 6 ton capacity trailer.
In basic form it cost £645 or £732 with auxiliary gearbox, larger tyres and cab.
The only coach built on the Delta chassis was this petrol engined, streamlined example that was supplied to Manchester City Transport in 1935 for their airport service. It had 20 seats.
