Clock Radios and Variacs

I have a Zenith table top clock radio at home, vintage late 50s or very early 60s (the set has the old Conelrad markers on the radio dial). The clock runs and keeps good time, and I'm hoping to keep the clock part running for a while. Are there any lubrication points on the clock motor as there are with pure mechanical (wind-up) clocks? If so, what type of oil should I use, or is there a shop that would work on vintage electric clocks?

It's been a long time since I've had an electric clock of this vintage, though I don't remember those old electric clocks ever needing any service for years and years until they just stopped.




Thanks,
Joe
