H&H Auctions is to offer a set of four vintage barn-find motorbikes and sidecars from the 1920s and 1930s.
They are among the headline lots of its November 16 auction at Donnington Park in Derby, UK.

They include a 1932 BSA G12 Combo used by police in Bath, Somerset, which carries an estimate of £18,000 ($22,048).
A 1925 Quadrant Combo is valued at £12,000 ($14,699).
Motorbikes from this era retaining their original sidecars are rare and so this collection is likely to attract a lot of attention.
Mark Bryan, H&H Auctions' motorbike specialist, told the Daily Express: "I would have been elated to find one of these old sidecars but to find four was astonishing.
"I could barely believe it at first, sometimes you just get lucky."
He explained that the owner bought the motorbikes a number of years ago and has only recently rediscovered them.
"The owner, an avid bike enthusiast, was going to open a motorcycle museum but it didn't work out so these were placed into storage."
"Over the past five years prices for bikes in this condition have sky-rocketed, people are now willing to pay big money for pieces in original condition.
"We've even asked the vendor to leave the bikes as he found them, as buyers appreciate them more that way."
