I came across the following YouTube video which features HO-scale racing from November 23, 1964. Its the final of a country-wide contest in the US and was incorporated into a popular TV show of the day called "I've Got a Secret". The grand marshal is Stirling Moss himself. Enjoy a little something from the roots of what we do now!
