Hi posting again as can’t see my original post, I have an old bonnet emblem passed down from my grandfather to my father and now to me from around the 1920’s. Family story is that a “Rolls” badly crashed in rural Ireland and my grandfather was called to help, the bonnet emblem was salvaged and sat in his garage for many years, now passed to me and I would like to research it, the serial/membership number is clear, is there an RAC resource for checking back or any archives I can used, tried online and so far drawn a blank, thanks
