Among the star lots being offered for sale by Bonhams at the 19th Carole Nash Classic Motorcycle Mechanics Show will be a 1929 Grindlay-Peerless JAP 500cc ‘Hundred Model’, one of only two known to survive.

The Grindlay-Peerless is expected to fetch between £50,000 and £70,000 when it is sold during the event at Stafford Showground on October 20-21.

It was built as a factory replica of the machine used by Grindlay-Peerless rider CWG ‘Bill’ Lacey when he became the first man to cover 100 miles in an hour on British soil in August 1928.

Only five or six such replicas were ever made and this one was used by a prominent VMCC member, the late Edmond ‘Boy’ Tubb, to win a gold star award by lapping Brooklands at over 100mph in 1937.

Offered for sale by the Tubb family, this Grindlay-Peerless has been displayed at the Brookland Museum since the late 1980s, and used by the Brooklands Society on numerous demonstration runs in recent years.

Other notable early consignments for the Stafford sale include a recently restored 1910 Rex 5hp De Luxe V-twin that has participated in the Pioneer and Banbury Runs since completion in 2007, estimated to make £14,000 to £18,000, and a 1930 Brough Superior ‘Overhead 680’ restoration project which is estimated at £20,000 to £30,000.

There will also be a collection of three Velocettes owned by world-famous motorcycling authority and prolific author the late Jeff Clew.

This includes a 1930 KTT racer, estimated to make £20,000 to £25,000, an ultra-rare 1929 Speedway model estimated at £7,000 to £10,000, and a 1957 Valiant expected to fetch £36,000 to £40,000.

All of these have been displayed at the Haynes Motor Museum in Dorset since Jeff’s death in 2009.

Raced at Brooklands and in the Manx Grand Prix by its first owner Harold Lamacraft and later at Brooklands by Bert Perryman, the KTT was restored by Jeff in the 1960s to be as close as possible to its original specification. Since the completion of this restoration in 1967, it has been ridden on closed roads over part of the Isle of Man TT course for the Manx Grand Prix’s 50^th anniversary in 1973, and also at ‘Brooklands Revived’ events.

Veloce Ltd made only 21 Speedway (dirt-track) models, and Jeff’s re-creation uses a genuine 415cc ‘KDT’ engine, basically an over-bored 350cc KTT unit, which is housed in a KSS roadster frame modified to dirt-track specification by many-times grass-track champion Lew Coffin.

Ben Walker, director of the Bonhams Motorcycle Department, said: “Brooklands machines rarely come to market so we are truly honoured to be offering not one but two important examples at our autumn Stafford sale.

“The ex-Edmond ‘Boy’ Tubb 1929 Grindlay-Peerless represents the period of ‘no fear’ motorcycle racing when Brooklands was the centre for the world’s most epic speed record attempts.

“Jeff Clew is sorely missed by all and we look forward to continuing his legacy through the sale of his much-loved and highly-prized Velocettes, one of which has Brooklands and Manx Grand Prix history.”

Free parking will be plentiful on both days of the show.

Gates are open 9am to 6pm on the Saturday and 9am to 5pm on the Sunday.
