Prior to Covid I looked at a more focused / specialist visit to Normandy, allowing for my memory the larger, well-known companies do not offer such tours except by special arrangement. Some of the British Army formations conduct staff rides, using external contractors and if they do one for the 6th Airborne Division that is who you need to identify. I understand there are specialist guides in Normandy who can arrange focused tours. Alas all the research has been shredded. Paradata who appears here might be a good person to ask; he is connected to the Parachute Regiment Museum.
