The Bedford Enthusiasts Club marked the 90th anniversary of the start of the vehicle's production with a convoy to Millbrook.
Drivers started at the northbound services of M1 junction 15A where the vehicles left in age-related order - oldest first.
Before making their way to Millbrook Proving Ground, the 24 vehicles visited sites historically significant to the make including Kimpton Road in Luton - site of the Vauxhall factory where Bedfords were made from 1931 until the name was dropped in 1991.

The vehicles on display ranged from a 1935 "W" model right through to one of the last "TL" models made in 1989.
Carl Lemon, Bedford Enthusiasts Club event organiser, said: “I came up with the idea of the Bedford birthday convoy in celebration of the 90th anniversary.
"Millbrook played a major role in the development of Bedford Trucks after its opening in 1970, so it was the perfect location for the conclusion of our event."
