Nisonger (http://www.nisonger.com) can calibrate Smiths mechanical speedometers. Worth checking with them beforehand whether the range of re-calibration you require is within the range of what's possible with the stock J-H speedometer. I had my speedometer recalibrated by Speedy Cables here in the UK, and they were able to achieve the required 15% correction in calibration without any issues.
