An Italian caption of the Wikimedia picture says: Miniature car with a combustion engine, replication of the model Riley Brooklands. Built in a single original, in the second half of the '30s, by Gustave Maclure, designer of the Rolls Royce and Riley, and his brother Percy, pilot of Riley, for his son Peter. With this small car, the ten-year-old Peter Maclure established the record for miniature cars, at the Donington circuit in 1937.
