Led by the ultra-rare George Daniels-owned 1929-31 ‘Tim’ Birkin Bentley that may set a new auction record for the marque, and an Ex-Works Le Mans 1932 Alfa Romeo 8C-2300 Lungo (est. $3.9m-$6.2m), Bonhams will offer no fewer than five distinguished collections at its auction later this week at the Goodwood Festival of Speed. A Bentley 3-Liter Speed Model Sports Two-Seater with coachwork by Park Ward (est. $200,000-$230,000) highlights the Peter Gwynn Collection, and a 1938 Bugatti Type 57C (offered without estimate) leads the pack from the noted collector John O’Quinn, who at one point owned 869 vintage automobiles.In addition, there will be 24 Lotuses at the June 29th sale from the Glasius collection—expected, as a group, to realize over $2m–and five cars owned by Sir Antony Pilkington, including an ex-RAC, Alpine & Tulip Rally 1957 AC Ace-Bristol Sports Two-Seater (est. $260,000-$310,000), and the ex-Marvyn Frankel 1939 Bentley MR-Series 4 1/4-litre Tourer with coachwork by James Pearce (est. $160,000-$220,000).
