Here is an original example of the last Claud Butler “Olympic rings” this was found on a 1987 Cape Wrath MTB built by Falcon. The badge is a version originally created by the previous owner of the brand, Holdsworth. But when the ownership transferred to Marlboro late 1985 in the Midlands, the ‘London’ from the ‘London England’ was dropped. The badge continued after Falcons takeover early 1987 and I believe survived until sometime mid 1988.
