Hard to say given the period. For example, c. summer 1944 none of the R.-Flotille were based in Calais, although some of the boats likely operated from there. As of 1 June 1944; 9. Flotille was at Vlardingen 2. Flotille was at Dunkirk 4. Flotille was at Boulogne 8. Flotille was at Brugges 10. Flotille was at Ouistreham 14. Flotille was at Dieppe So probably 2. or 4., but it could be any one of them. If we could see a hull number that would pin it down.
Interesting...I thought the camouflage was added later. If it was Calais in late 1940 and early 1941 they were probably 4. Flotille, R41-R52.
Hello Richard, thanks again, the problem is that 4. Räumbootsflottille (Boulogne) had another scheme of camouflage at that time. regards, Cnock
Ah, sorry about that. If it is the SEELOEWE period you have a limited number of choices, 1., 2., 3., or 11.
