The decommissioned Royal Navy warplane, which saw active service in the Falklands in 1982, is currently sitting in the yard at Keltruck in West Bromwich.
 
The company normally deals with Scania lorries but was offered the Sea Harrier in part exchange for a truck and couldn't resist the challenge.
 
The jet has become something of a novelty for visitors to Keltruck's headquarters on junction 1 of the M5 motorway. But it is not just there for show - the company is now auctioning it on eBay, the online marketplace. Chris Kelly, Keltruck's Chairman, took the jet in part exchange for a second-hand Scania truck from Lincolnshire-based Witham Specialist Vehicles, which sells and markets ex-Ministry of Defence vehicles and plant equipment.
 
Mr Kelly said: "We have taken some unusual things in part exchange over the past 25 years, including pallets of bricks and even live sheep, but this is certainly the most unusual.
 
"The Harrier has caused quite a stir locally with people having assumed it was flown in but it has actually been decommissioned and arrived on the back of a lorry.
 
"People just couldn't believe it when it arrived. It was one of the last Sea Harriers to come out of service, with the remaining ones that could still fly being sold off to the Indian Air force.
 
"Now we are advertising it on eBay but will obviously be looking for thousands rather than millions of pounds. It will probably go to a collector of militaria or someone like that."
 
The BAE Sea Harrier was renowned for its vertical take-off and landing ability - hence the nickname jump jet. It first entered service with the Royal Navy in April 1980 and was withdrawn from service in March this year.
