Donald Cowbourne's three "British Trials Drivers" books provide the most comprehensive record of car trialling Pre WW2. Austen May's classic, "Wheelspin", may provide his personal view of trialling in the 1930s but Donald Cowbourne's books provide all the facts and figures on all the major events from 1902 to 1939. Absolutely unparalleled and totally essential for anyone with a serious interest in the history of trialling.

Donald Cowbourne's books are no longer available from the publisher. They are now available from Clinton Moore (mbpa@c-pbm.freeserve.co.uk) who has the sole distribution rights for the original print run. The books are now £25.00 each + £5.00 postage to UK addresses. There is a special offer of £100 with free postage (within the UK) for those buying a set of all four books at the same time. For postage costs to overseas addresses, please contact Clinton Moore at the email address above.
Second hand copies do appear from time-to-time on AbeBooks or Amazon, or through specialist motoring booksellers, or at autojumbles, but don't be tempted by some of the extortionate prices being asked when brand new copies are still available.
More information is available at www.ralliesandtrials.com although please note that the prices are out-of-date.
Soon after I received news of Donald's death, and perhaps anticipating that the books would become unavailable in the not too distant future, I printed the Update pages from the publisher's website and reproduce them here as PDF files.
With thanks to Greg Wrapson, who provided me with the scans of the original articles.
