THE CROSSLEY KEGRESSE

The British War Office issued a specification for half-tracked vehicles in 1923 and ran a competition in 1925. Crossley signed a licencing agreement with Citroen-Kegresse on 19 January 1925 and entered a BGT with Kégresse tracks at the trials which was held in February. Crossley came out best in the trials and orders were placed for 15-20 cwt and 3 ton chassis. 115 in total were ordered by the British Army and RAF, 55 of which were for the 15-20 cwt models.  An unknown but small number were also sold privately.

The Kégresse option was available on the following chassis -

Model chassis number range payload date
15-20 cwt 25xxx 15-20cwt 1925-7
IGL2 30xxx 3 ton 1926
BGV 1 and 2 60151-60195 15-20 cwt 1927
BGV 3 and 4 6xxxx 20-30 cwt 1929

One experimental IGL with a "positive drive"  track and rated at 4 tons was made in 1928.

One complete and possibly two partial vehicles are believed to survive.
