More than 1,000 people flocked to Camp Farm near Thetford this weekend as Norfolk farmer, Paul Rackham put more of his personal collection of vintages tractors under the hammer.
Following on from the record breaking sale in September this year, Mr Rackham sold what was considered to be the most complete group of vintage Ferguson tractors and implements in the world.
73 tractors and 100 implements, together with other memorabilia and literature of the Ferguson Hunday collection fetched more than £500,000 - exceeding the expected price of £400,000.
This included £8,400 paid for a Ferguson beet topper - a record price for a Ferguson implement.
Among the highlights of the auction was a 1937 Ferguson Brown Type A which sold to a Scottish buyer for £15,000, £3,000 above its top guide price.
The model was the first ever machine to be fitted with converging three-point linkage and a hydraulic lift incorporating automatic draft control, which is a system at the heart of every modern tractor.
Another top price went to a fully restored MK1 long wheelbase Land Rover. Sold to a buyer from southern Ireland for £36,000, this item fetched in excess of £11,000 its top end guide price.
In the memorabilia section, a demonstration model Ferguson in its original, unrestored wooden box with running boards, trailed and mounted ploughs sold to a buyer in Cumbria for £4,100.
A selection of Ferguson Brown literature sold for £800 while a neon Ferguson dealer sign went for £2,200.
Organised by Cambridgeshire auctioneers, Cheffins, auctioneer Oliver Godfrey said: "It was a real pleasure to be involved in the sale of such a historically important collection.
"It was an excellent auction and generated a huge amount of interest, both at home and abroad, with buyers from Norway, Sweden, Hungary and even Australia, as well as Harry Ferguson's native Northern Ireland."
Mr Rackham said he was delight with the result of his most recent sale and would now be focusing on a new challenge.
