History and Heritage
Jensen At War | Jensen Motors 1939-1945
The world changed in 1939, with Britain declaring war on Germany in September 1939. Most car production in Great Britain stopped in its tracks, and very quickly the government was issuing out contracts for a huge variety of war-driven vehicles and materials.
Veiled in secrecy was the wartime exploits of Jensen Motors. Incredibly, this small vehicle manufacture was at the forefront of wartime production, producing bomb casings, tank parts, and even one off tank conversions. It was no wonder that this West Bromwich Company was to end up on the Luftwaffe’s ‘Hit List’.

Jensen Motors was one of many small Midlands-based companies finding themselves with a range of military-related contracts. The Company already had a history of building a range of commercial vehicles, so some of the government contracts were for small military vehicles.

Jensen had also been building fire-engines and ambulances pre-war, and so manufacture of these continued. Both very much needed for times of war.
Specialised work came in which kept the trim shop busy, with contracts for the trimming of aircraft seats, and barrage balloon facings.
However, the Company also received large armaments contracts for the manufacture of bomb casings and bomb crates. Work that would undoubtedly come to the attention of German intelligence.

Armourers show off bombs for a comparison in size at the bomb dump at Woodhall Spa, Lincolnshire during the 1940s. Jensen Motors received various government contracts to supply bomb casings, with particularly large contracts to supply 500 lbs bombs.

Other specialised work included the making of revolving gun turrets, and various conversion work to tanks. Later in the war, the Company was even asked to overcome problems in converting the Sherman Tank for amphibious, use leading up to preparations for the D-Day invasion.
With so many contracts coming in from the War Department, it would be necessary for Jensen Motors to constantly advertise for employees throughout the war years.

Jensen Motors were tasked with undertaking a conversion to the basic Sherman tank, to make it amphibious. This was on the lead up to the D-Day invasion. Jensen created a simple but clever waterproof canvas system that could be raised up over the turret area. Various additional waterproofing work had to be dealt with under the tank, and a double propellor system was fitted to the rear, which ran off an additional drive to the engine.

Jensen At War | Jensen Motors 1939-1945 | Bombing Raid
During a bombing raid by the Luftwaffe in November 1940, Jensen Motors Carter’s Green factory took a direct hit. Although much of the factory remained unscathed, there was some inevitable destruction.
The Luftwaffe’s November bombing raid unfortunately led to the loss of much of Jensen Motors’ pre-war files and records. However the raid did not hit the main factory buildings, and as such, wartime work continued unabated.

As with the Allied bombardment of Germany later in the war, Germany’s Luftwaffe were looking to destroy strategic sites, particularly factories manufacturing military hardware for the war effort.
It is very likely that German intelligence knew that Jensen Motors were manufacturing military hardware, including bomb casings, and that the Carter’s Green factory was a Luftwaffe target.
Jensen At War | Jensen Motors 1939-1945 | Wartime Employees
Throughout the war years, Jensen Motors were constantly advertising for employees. With much of the young fit male workforce away at war, women were signing up to work at Jensen Motors.

Employee lists from the time, gives us an insight to some of the jobs that female employees signed on for. As will be noted, the majority of those women joining Jensen Motors during World War II, left at the end of the war, or shortly afterwards.
This would be due to the shift back to the traditional manufacture of cars and commercial vehicles, and probably Jensen Motors needing different skill sets.

Jensen At War | Jensen Motors 1939-1945 | An End To War
Towards the closing stages of World War Two, Mercedes-Benz were secretly planning the resurrection of the Company in a defeated Germany.
Talk of Defeatism wasn’t tolerated in the Germany of 1944, and had such secret planning become publicly known, it would have led to the possible summary execution of those involved.
In Great Britain, it had looked as though the tide was turning by 1944. The Jensen brothers could look positively to the future within a victorious country. They, like Mercedes-Benz, were planning for a post-war era.

An early 1944 Jensen Motors advert, with a photograph from a pre-war Earl’s Court Motor Show. Using a question mark to the exact year, this advert suggests the war will soon be won, and that Jensen Motors will be at the fore front of vehicle building in the post-war era.

Jensen Motors ‘After Victory’ advert from December 1944. With an Allied victory imminent, Jensen Motors were keen to let the public know they would once again be in the forefront of luxury car production.
It was obvious to both Mercedes-Benz in Germany, and to Jensen Motors in Great Britain, that the first product that would be much needed in a post-war era, would be inexpensive lorries of all different types. Both Companies had lorry-based projects on the drawing board before the end of the war.
However, the Jensen brothers were also planning a new motor car, which could be presented to the public directly after the end of the war. This new car would be known as the PW saloon. The ‘PW’ designation simply meaning ‘Post-War’.

With a plan in place, the Jensen brothers waited for the victorious outcome. They didn’t have to wait long, with the war coming to an end in May 1945.
Directly after the end of war, Jensen brought out their JNSN lorry. The Commercial Motor magazine from 9th November 1945, offered a three page feature about the new JNSN lorry. The feature was headed, ‘A New 30 m.p.h 6-Ton Oiler with Light-alloy Chassis-cum-body’.
Meanwhile work on an economic and versatile lorry, named the Jen-Tug, started, along with their new motor car, the PW Saloon. The first of the PW Saloons was made available to the public in summer of 1946, and production of the Jen-Tug was made ready by the end of 1946.
