To add my two pen'orth, I would remind members, as I have posted elsewhere, that I believe the late Frank Dyer of Dorchester fame was one of the first to use the 16.2mm gauge. Back in 1980 he built the track for Dyers End station on the MRC's New Annington layout. He explained that was to 16.2mm gauge and that all RTR stock and BRMSB wheeled stock would run on it. He was right, it did, and it looked better than 16.5 gauge.
I built most of the rest of the track, along with help from others, to 16.5 gauge.
