I think you'll find 'twas the other way round: the spring clip was the original Austin fitting, the cast block was found on aftermarket replacements - new old stock ones with the solid clip cropped up quite frequently in the 1960s. They came in a green and black box similar to Remax components, although I'm not so sure they were marketed by Remax.
