I live just opposite Gypsy Lane which is inbetween Barnes & Putney. SW15. There is a barber shop there which has been used for at least two, Ray Daley 'Minder Episodes'. I think one of them is possibly 'The Greatest Show in Willesden', but I haven't got a copy of the episode so sadly can't check :-( I went for a haircut there the other day and the old chap there was giving me the run-down of the filming. They also have pictures of George Cole, taken during the filming, on the shop walls. I will get a photo of the shop when I nip over to the parade of shops were it is :-)
