Hi Martin,
Sorry to say yours is not a Comerfords Cub, I have a 67 Commerfords which I purchased in South Africa, there were two (2) brought into the country and one (1) is still there, mine is now in the USA.
I have used it since 2008 in modern trials but, unfortunately I have "modernized" the steering angle and foot rest position but retained the oil tank and fuel tank. Should you want any photos please message me back and I will send them.
Kind regards,
Nick
