Hi, I don't want to hijack your post but interested in Bernards reply, if anyone knows he does, just when he says Mk5, if you look at a Mk5 Siffert apart from having a tachy bezel they also have brushed finish hands with blue inserts not steel and black inserts, is there another 'Bell' Mk covering MH bezel 3-6-9 subdial, white infill hour markers, brushed hands with red infill. Probably been discussed already but I have not come across it.
