Some of the broadcast oscilators for TV transmitters were pricey. The oscilator manufacture wanted $980 to replace a bad unit. The transmitter manufacture wanted $1800 for the same unit. 

They are not true Time Nut quality but I've used them as a reality check when trying to figure out what is drifting. It has also been used as an example of a vey low noise oscilator. 

Check it out and see if it drifts to much for your precision use.
