Pisces, which was a Small Northwich, had a rachet lever throttle control, and a very long pivoted lever connnected to the gearbox for gear change. I do not know whether they were original equipment, or controls fitted when the boat was either converted into a Fire Boat, or later into a Water Bus, but they were the controls on the boat when aquired from Brittish Waterways in the early 1960's. I seem to remember seeing another former working boat with a similar arrangement some years ago, but cannot remember the name of the boat.
