I originally used a 184 Time Mark Generator for some of my broadcast measurements where I needed 10 kHz markers throughout the AM broadcast band. I don't recall it having drift anywhere near that amount. I wonder if your oscillator tube is on the verge of croaking or if the stone has become feeble. I don't think these devices needed a great deal of accuracy, certainly by "our" standards, just enough to set the time base adjustments in a scope.
