This sales catalogue from 1926 is not complete and its front cover is missing but it had at least 18 pages, of which the 8 remaining pages are published here. The value held within these pages makes it worth while, and the models include the Big 4 6.33hp, the 16H 4.90 Sports, the Model 18 OHV, and 4 of Nortons sidecar models, with the Family and Semi Sorts Touring just 2 of them.
