There's a chap involved with the airfield who is looking to start a museum on site, dedicated to RAF 19 Sqn (who operated from there, as a satellite of Duxford, during the BoB) , and the 339th FG who flew their Mustangs from Fowlmere. I'm hoping to meet-up with him during my next visit to Bottisham's embryonic museum, and have a chat, see if I can help in some small way, as with Bottisham.
The two Nissen huts and the cow / pig shed, often mentioned in accounts of the airfiels, and seen in numerous photos, mainly from the BoB period, are still there, and there's a small memorial stone too.
The main (grass and PSP) runway threshold was in the field immediatley behind the tree line where we were sitting, probably less than 100 yards away.
The other pub in Fowlmere village (The Chequers) have their pub sign with the blue and white checks of 19 Sqn on one side, and the red and white checks of the 339th on the other side, in memory of thr two units. It's the pub I was going to take you all to, after we'd had dinner at The Coach House, but time and fatigue caught up with us all.
