Hi DBenz

Thanks for the suggestion. I did try the air gunners museum last year. We sort of arranged to be allowed to measure up a turret but as we approached the airfield it soon became clear that we had chosen possibly the one day of the year when they were holding a massive air show!! Got to see the Lanc fly over and had a good time, great re-enactors, but the suggestion that we might measure a turret was a no-go. We did return but in fact they don’t have an FN4, they have the later turrets but it appears that one of the improvements to the turret was to remove this rather convoluted chute system, so none of the turrets there have the system shown.
