A look see at what is cooking in Britain's armouries...
Light Tank Mk VI (A14): Designed by Vickers as a private venture in 1936 this is a wholly new design. New independent spring suspension uses large road wheels and flexible track steering. Production will be undertaken by Metropolitan-Cammell. The 165hp Meadows petrol engine provides a top speed of 40mph on roads and 20mph cross-country. Range is 140 miles. The armour is 14-4mm thick and the armament is one 2pdr QF Mk IX and one co-axial Vickers K MG. Only two crewmen are carried.

Cruiser Tank Mk III (A13): Lt. Colonel G. Le Q. Martel, recently appointed Assistant Director of Mechanisation, on witnessing trials of the Christie type suspension in the USA suggested a much faster tank could be built using the A10 chassis with the Christie suspension. A trial vehicle designated A13E1 was built in mid 1936 by Morris Motors for trials. The "trackless running" feature was removed as an unnecessary complication and the second trials vehicle the A13E2 featured the turret of the A9 and a 300hp Nuffield V-12 engine. Speeds over 30mph were obtained and this formed the basis of the proper A13 tank Designed by Morris and Nuffield the A13 is powered by a 300hp Nuffield V-12 offering a top speed of 30mph on roads and 24mph cross-country. Range is 90 miles. Armour is 25-6mm and the armament is one 2pdr QF Mk IX and one co-axial 0.303in Vickers MG. The crew comprises four men including a radio-operator. 65 initial vehicles will be built by Morris Motors, Crawley, Oxfordshire, and the following 200 tanks will be built by Nuffield Aero & Mechanisation, Cowley, Oxfordshire in a new purpose-built factory in a joint programme with Morris.
Infantry Tank Mk II (A12): Vickers is currently working on a new Infantry Tank armed with a 3.7in howitzer and a top speed of 16mph. Prototypes are to begin testing in late 1936. Armament is a single 3.7in QF Mk II with a co-axial .661in HMG and the armour is 76-10mm thick. Two 87hp AEC diesel engines power the tank to 16mph over 160 miles. 140 will be completed by late 1937 by Vickers.
[The Matilda II but with revised armament]
Guy Wheeled Tank: A private venture begun in late 1936 by Guy Motors based on their Guy Quad-Ant four-wheeled drive artillery tractors but with an all-welded mild steel body and a turret with a single .661in Vickers HMG and a co-axial .303in Vickers MG. Top speed is 55mph and range is 210 miles. Production versions will have armour 15-4mm thick.
Daimler Scout Car Mk I: In response to a 1936 requirement issued by the Mechanisation Board for a light turret less scout car three companies offered prototypes which were tested during 1936. Alvis offered its small 'Dingo' which weighed 2 tons and was armed with a single Vickers 'K' LMG, BSA offered a smaller and cheaper design and Daimler DSA Ltd offered a very similar design. All were rear-engined and were roofless. Daimler was offered a production contract on the basis of very successful trials. This two man car weighs 2.8tons and is powered by a 55hp Daimler petrol engine, has a top speed of 55-60mph and a range of 260 miles. Armament is a single Vickers 'K' machine gun and four-wheel drive is fitted and production models will feature a folding roof.
Carrier Machine Gun No.1 Mk I: About to enter service this light 3.15ton tracked vehicle has a crew of three and is armed with a dismountable .303in Vickers. It has 10mm thick armour. The same chassis forms the basis of the Carrier Mortar No.1 Mk I with a 3in mortar and sixteen rounds of ammunition and the six-seat Infantry Carrier No.1 Mk I armed with two Lewis LMGs. All three will enter service in 1936. The observation OP Carrier No.1 Mk I with radio equipment, cable drums and a steel roof will enter service in 1937.
[The Bren Gun Carrier by another name]
Ordnance QF 25pdr Mk I, is under development from mid 1935 for service from 1937 to replace the 18pdr and to have a secondary anti-tank role.
Ordnance QF 4.5in Gun Mk I, under development to fire a 55lb shell over 21,000 yards. To enter service in 1936. Weight in action is 12,880lbs, 55lb shell weight of which 3.875lbs is HE filling. Maximum range is 21,500 yards and the carriage has 60 degrees of traverse and 30 degrees of elevation.
BL 7.2in Howitzer No.1 Mk I, entering development to enter service in 1937.
Ordnance QF 3.7in Mk III, is under development by Vickers partly as a private venture, firing trials to begin in 1936. It is based on a similar Naval AA gun. Weight in action is 9.2 tons mobile and 17.1 tons static, effective ceiling is 32-45,000 feet and ground range is 20,600-25,600 yards. Rate of fire is 25 rpm on the mobile mount and 19 rpm on the static mount. Elevation is 85 degrees on the mobile and 90 degrees on the static mounts.
