An outstanding 1960 Maserati Birdcage will be among the automotive highlights at RM's Sporting Classics of Monaco, which takes place on May 1.
The Birdcage, Chassis 2470, is one of only 17 Tipo 61s built and has a very competitive racing history - beginning with its first owner, the eccentric Texas oilman Jack Hinkle.
Hinkle achieved stellar racing results and numerous victories in this car in various historic races, pushing the Birdcage's 250bhp, 2,890cc overhead cam inline four-cylinder engine to its limit.
Inside the Birdcage is the very best 1960s Maserati engineering. Its "Birdcage" nickname comes from its unique and very innovative trellis chassis construction, made of a plethora of small tubes between 10-15 mm thick.
Once welded together (all 200 of them!), they created a structure as rigid as it was light; weighing just 36 kgs and clothed in svelte wheel-hugging aluminium body.
One of the most original Birdcages in existence, it is fitted with a spare race prepared engine - although the original engine will be included in the car's sale.
The Birdcage will auction with an estimate of €2.4m-2.6m.
