It was thought for some time that YM1.551 (Reg.No. 9915NO) and YM1.552 were at the 1958 Earls Court Motor Show, but current information contradicts that.

From Autocar 24 Oct 58 (p 559):
M.G. -- 154

A white fixed-head coupe with wire wheels, and a red [Pushrod # 56686] open two-seater with a number of accessories are the two models of the M.G. MGA on open display on the stand. There is also a partially sectioned model of the MGA Twin Cam Coupe. It is finished in sandy gold with the roof in powder blue (still visible on the BMIHT car), and a yellow interior. This car is on a revolving turntable, and cunningly arranged mirrors show the chassis details. The standard MGA, powered by the M.G.-tuned B.M.C. B-series engine, is undoubtedly one of Britan's most popular sports cars, and it is not surprising that it is to be continued without change for 1959.
As last year, a Magnette is on show to which Perspex boot lid and bonnet have been fitted, enabling visitors to inspect the engine and luggage compartments without raising the lid. This car is finished in an attractive shade of steel blue. There is another Magnette with optional extra Varitone paintwork, beige over maroon. Both the Magnettes and the left-had drive MGA coupe have whitewall tyres.

The MGA Twin Cam cutaway display was produced by the M.G. Show Shop at Abingdon for use at the New York Motor Show. It was later lent to the Longsight Police Driving School and remained there until it was taken to the British Motor Industry Heritage Trust Museum at Gaydon, where it is now on display with a larger portion of the body work removed.

The sectioned MGA YM1.??? Twin Cam Coupe displayed at a recent car show. "Car No." is blank on the ID plate, so all we know for sure is it was very early production Twin Cam, or possibly a model shop fabrication that never had a chassis number. If the opportunity ever arises, someone needs to do a closer inspection of the car to see if it has a chassis number stamped on the frame.
