There were one or two RLGs/ELGs in the vicinity which I presume were part of the wartime EFTS. One was at Crazies Hill on the road to Henley from Burchetts Green, another at Cock Marsh south of the Thames opposite Cookham. I did hear a rumour of a third between Marlow and Cookham, just east of the Marlow bypass where the gravel pits are.
