In reply to Al Evans: Incidently another book of possible interest is Tom Fairbanks classic 'I Bought a Mountain' with a description of an early succesful attempt on the Welsh 3000's.
"His first book, an autobiography entitled I Bought a Mountain (ISBN 978-1871083057) was published in 1940 and became a major international best-seller. It describes how aged only 21, he bought he bought Dyffryn Mymbyr farm,[1] a 2,400-acre (9.7 km2) sheep farm in Capel Curig, North Wales, in 1931 and painstakingly learnt his trade, while portraying the beauty of Snowdonia. Firbank was a keen mountain walker, and the book includes a hair-raising account of how he and his two companions were possibly the first to ascend all of the Welsh 3000s in less than 9 hours.[2] Firbank's first wife, Esme, a Surrey-born actress whom he met in 1933, features prominently."
