We had specified that the existing main drive was to be enlarged with the original sets (Marshalls Tegula). Brindle sets (not Marshall's) were produced but then corrected. Pressure was put on me to pay before the job was completed but I resisted. Had a quick look at the wall on completion at about 8.15pm by torchlight and paid by bank transfer. In daylight noticed the wall is not completely symmetrical. Perhaps it is difficult to achieve 2 identically curved wall tops on such a short stretch of wall e.g. 28.5 red bricks on left curve, 24 on right). Job was extended to include replacing the edging to existing gravel part of drive, which went very well.
