Harespares AKA Autorama were not themselves a tuning company and as far as I am aware they didn't offer any of their own parts. They did however offer a superb (possibly the best of the lot) colour mail order catalogue which detailed tuning equipment from many of the leading 60's tuning houses.

I have posted some 25 scanned pictures from the 1966 Autorama catalogue, follow the links below to see some of their range of tuning equipment. Once again, thanks to Karsten.
