Two Formula One trailers used by 2009 world champions Brawn before being bought by the would-be US F1 team have been put up for sale on eBay after being seized under a court order issued by a British creditor.

The US-based team had been due to enter the championship this season but failed to build a car in time due to financial problems.

"It's quite sad news in a way but inevitable in this sort of climate," David Carter, director of The Sheriffs Office debt collection company responsible for enforcing the writ, told Reuters on Monday.

"The High Court writ was issued against the US team and these are the only assets they had over here...and eBay is a good way to create a lot of interest."

The trailers, still in Brawn livery and one with world champion Jenson Button's name and number 22 on the side, will go to the highest bidder without a reserve.

When new, they carried an estimated price tag of around 300,000 pounds ($462,900) each.

One trailer contains an office with space for 10 engineers. The other has a machine shop and space to carry three race cars and equipment.
