Only one in Sussex listed.
On a more serious note: Try a visit to Shoreham airport which is still in use. (I mean the one near the coast not the other one). They have an interesting museum. The airfield was opened in around 1911 so it's got to be one of the oldest.
It would be worth giving them a call and see if you can get a look at the 1910 Lee-Richards Annular biplane I hear they are building.
Someone told me that the first air cargo flight to leave the UK departed from Shoreham.
