The collection includes a 1917 Holt 75 - one of only four examples known to exist in the UK.

The tractor - described as "iconic" - was feted in both the UK and America and was in production from 1914 – 1924.

It mainly supplied the British, French, Russian and US armies during the First World War and was used as gun tractors to haul heavy Howitzers and for supply trains.
