This P107 kegresse half track belongs to George Williamson, this was the first time it has been seen in public at the War and Peace revival, since it was found and recovered from Normandy. George then set about the restoration which took a number of years.Production of the Unic Kegresse P107 half-track started in 1937 and just over 3200 were produced before the German army occupied France, many were used by the Germans as troop carriers and gun tractors, some were modified with armour and some were fitted with the 2 cm Flak 38 anti aircraft gun.The history of the Kegresse track system goes back to before the Great War. Adolphe Kegresse was born in France 1879, in 1905 he moved to Russia and was soon working in imperial car park for Tsar Nicholas II and also becoming his personal chauffeur . It was here that he invented the Kégresse track system which he used to convert the Tsar’s motor vehicles into half-tracks which improved their off road ability. After the Russian Revolution of 1917 Adolphe returned to France where he became friends with Andre Citroen, by 1919 he was in the employ of the Citroen Company working on his design for half tracks. The company began to produce vehicles based on Citroen cars using the Kegresse track system between 1921 and 1937. They were made for off-road use and also used as military vehicles.Citroen set up a new department called Autochenilles in his factory near Paris and appoints Adolphe Kegresse as the technical director. To promote the abilities of the new vehicle Citroen launched several large scale promotional campaigns. The first being the crossing of the Sahara between December 1922 and January 1923. The final epic journey in 1934 was starting from Syria crossing the Middle East and China ending up in Pekin. You watch a very interesting film on the crossing on the link below on our Youtube channel.
Adolphe Kegresse retired in 1935 after the death of Andre Citroen. The Kegresse track system was then taken up by the Unic company who then began producing the P107 kegresse half track.
