Re the tower at Podington. The only thing that might be important here is that it has been used as a residence for some considerable time. I'm pretty sure it was converted in the 1970's. That might well have put it outside the main body of 'listings'. If you're interested in what the particular rooms were used for I would suggest a visit to East Kirkby. The Licolnshire Aviation Heritage site. The tower there is, I believe, a 12779/41. However, it has been excellently restored with all the rooms restored to their original use with appropriate equipment installed. Although East Kirkby was a bomber field I'm sure there are quite a lot of parallels. A basic rule seemed to be that Met operated from the ground floor and ATC/Ops from the first. East Kirkby used to allow fly-in visitors but I believe this is no longer the case. Being a Sturgate resident you've probably been already.
