The truck, which is being put up for sale by the late owner's son Dean Hudson and bares the Hudson name, is said to be the only fully working model in existence.
The historic vehicle was originally used to transport steam trains, huge boilers, heavy girders and much more.
Commenting on its sale, Dean Hudson said: "I grew up helping my father hand paint, polish and restore the Scammell, which is fondly known as 'Leaping Lena' because it used to jump when pulling heavy loads up steep slopes.
"Since she returned to our family in 2018, after being displayed in the British Commercial Vehicle Museum in Leyland, Lancashire for 30 years, we have restored her to the tip-top working condition buyers will see today. And I can safely say that she is a pleasure to drive."
The new owner will need two helpers to operate 'Leaping Lena', as it takes three people to crank the truck into action.
Ritchie Bros territory manager Laura Roberts commented: "This really is a very special listing for us at Ritchie Bros and just like any piece of equipment the Scammell Truck has undergone a rigorous inspection by one of our specialist inspectors.
"Every detail of the inspection, including pictures and videos, is covered by our guarantee, so buyers know that the truck's condition will be exactly as listed."
