IF the gauge is accurate, 210 is about right for a 195* thermostat. The temp on the t-stat is the point it is supposed to start to open, not the temp it maintains. The operating temp will be 10~20 higher then the start to open point.

Don't assume the 31 year old gauge is spot on. Even a 5% variance is +-10 at 200.

Buy or borrow a laser temp reader and check the temp at the t-stat housing and entry point into the radiator once the motor is at operating temps.
