The Brooklands Society, who care for the history of the earliest purpose built racing track, which opened in 1907 and closed in 1939 at the start of World War II, issue a very nice quarterly A5 size magazine, the Gazette, which contains historic articles and period pictures.
 
These cater for races of both racing cars and motorcycles of all sizes and capacities and make a very worthwhile read.
 
Makes like MG, Bugatti, ERA, Delage and many others are featured
