Specific: The CitroŽn K1 which was based on
the CitroŽn type B2, was
bought in 1923 for evaluation purposes and was licensed
"HtK 129". Acquisition price was around
12.000,- Danish kroner. The performance of the CitroŽn
was tested in summer 1923 and winter 1923/24 (note ski on
front-wheels). The tests went well and in 1924 further 2
CitroŽns P7T (licensed HtK 75 & HtK 244) were bought.
The vehicles went through extensive testing and after
some years they were all worn out.
Note the extra cooling air louvres in the hood.
In 1932 a new 18 hp CitroŽn P17 (35 kb) was delivered and
the 3 worn out 10 hp Kegresses went back to CitroŽn as
part of the payment.
One of the tasks foreseen for the Kegresse-vehicles was
to perform reconnaissance for artillery-units.
Historical: The Kegresse-drive, which
was mounted with a endless rubber band was invented in
1910 - 11 by Adolph Kťgresse, a Frenchman who had worked
as technical manager for the Russian Czar Nicholas II
from 1906 to 1917. Mr. Kegresse converted the Packard and
Rolls-Royce cars of Czar Nicolas, as well as some
Austin-Putilov armoured cars.
A lot of Packard trucks were converted with the
Kegresse-drive in 1915, and used as ambulances.
Other companies like Caterpillar and Holt in the United States had toyed
with the idea of a halftrack, but Adolph Kťgresses solution with a
rubber band gave a more comfortable ride, and didn't tear up the road
After the revolution he returned to France via Finland
and, in conjunction with Mr. Jacques Hinstin, produced a
boogie which was adopted by Andrť CitroŽn in 1920.
In 1922, five CitroŽn-Kegresse K1 vehicles successfully
completed the Trans-Sahara Expedition crossing the desert
to Timbuktu. Two years later, Georges-Marie Haardt and
Louis Audion-Dubreuill used CitroŽn-Kegresse vehicles to

Other known users were Belgium, Chile, Germany, Great
Britain, Italy, Japan, the Netherlands, Poland, Spain and
