The oldest known surviving baby Rolls-Royce, a 1921 Goshawk cabriolet, will go up for auction April 29th in the UK. The 20hp cabriolet was the fourth experimental vehicle created to test a new chassis which was meant to replace the one on the aging Silver Ghost.

Originally fitted with a Hooper touring body, the car was used by Sir Henry Royce and chief designer Ernest Hives. In 1925 the car was equipped with a new engine and sold to a private owner who fitted the car with a cabriolet body by T H Gill & Company. Featuring a three speed gearbox and brakes for the rear wheels only, the classic car carries an estimate of £30,000-£50,000.
