There are a few old buildings and a hangar left but I don't think that the company will welcome anyone wandering around. It is classed as an industrial site.
If you PM me I can put you in touch with the secretary of the Memorial Garden. She might even meet you there.
My cousin died 30th June '44 on the Villers-Bocage raid with 51 Squadron.
There are books available with the history of the Airfield and the Squadron and they are low in price.
