After developing a model gyro monorail in 1911, he designed a gyrocar which was built by Wolseley Motors Limited and tested on the streets of London in 1913. Since it used a single gyro, rather than the counter-rotating pair favoured by Brennan and Scherl, it exhibited asymmetry in its behaviour, and became unstable during sharp left hand turns. It attracted interest but no serious funding.
The gyrocar was rediscovered in 1938, when workmen uncovered its remains in the Ward End property of Wolseley. Although it had been buried it was said the chassis was in excellent condition, the engine turned over and the gyros still pivoted, the main issue was damage to the aluminium bodywork. After being excavated, it was transferred into the Wolseley Museum.2
