Well, did not make Eastern Command Line due to distractions - its at least a 1 1/2 hr drive, so visited Benacre area instead. Many pillboxes in this area so will detail the visit in a few bolgs. First up are a couple of Suffolk Squares, which are as far as I can see unrecorded (at least they are not on the DOB data base I've got). Both are constructed using wooden shuttering as opposed to the pre cast blocks you find further south. Both have obviously been used post invasion role to test direct weapons fire against embrasures.
