FP-4 and FP-5
Vickers offered the Danish army an opportunity to borrow a Carden-Loyd Patrol Car Mk VI. This was called FP-4, and after six weeks of testing, the army was ready with a summary. It wasn't as good as the newly purchased Citroen-Kegresse truck in rough terrain, and on road it was hard to control. Moreover, the tracks fell off frequently. But it was cheap to buy and to use. This resulted that the army purchased two similar vehicles. The original FP-4 went back at the factory and one of the new tanks recieved the designation FP-4, and the other FP-5. When the army recieved these tanks, they saw, that these were of another version and in worse condition than the borrowed specimen. Vickers had to send people to repair the tanks several times. These vehicles were in service 1932 - 1937. In the pictures, the borrowed specimen is the one with the two men in it, the others are the units purchased.
