A tractor bought from a Stowmarket dealer back in 1939 is set to go under the hammer on Saturday, July 15.

The Marshall Model M, which has been in the same ownership since new, was bought by the vendor’s grandfather, Edgar Case, in 1939 and has remained on the family farm at Withycombe, near Minehead ever since.

The tractor comes with original paperwork including correspondence letters with the Geo Thurlow and Sons of Stowmarket, the supplying agents.

The very rare tractor was purchased for £643 and now carries an estimate of £18,000 to £20,000.

The tractor forms part of Cheffins’ July Vintage Sale, which takes place at Sutton, near Ely.

The sale features an rray of classic and vintage tractors, classic motorcycles and a number of other collectors’ items.

Among the tractors on sale is an important collection of 19 classic and rare machines from Norfolk.
