Fred Dibnah's steamroller in Great Dorset Steam Fair record attempt
More than 100 vintage steam rollers have attempted to flatten the world record for the greatest number in a parade formation.
The attempt at the Great Dorset Steam Fair, near Tarrant Hinton, featured a 10-tonne roller once owned by late celebrity steeplejack Fred Dibnah.
The current record, which is also held by the fair's organisers, was set in 2003 and involved 32 steam rollers.
Guinness World Records said it takes up to six weeks to verify an attempt.
The attempt featured 102 steam rollers, including "Betsy" which was owned by Dibnah and now belongs to his sons.
The requirements for the attempt, which took place on a newly-created 80m-long (260ft) section of road at the showground, included the fact the vehicles had to be moving.
It was adjudicated by independent witnesses on behalf of Guinness World Records.
More than 200,000 people visit the steam fair each year at the 600 acre-site, which also includes motorcycle and vintage tractor exhibits.
