I found this in a Rolls Royce Silver Shadow It is not OEM.

Aftermarket voltage regulator.

Not tested.  30 day guarantee. 

From VIN LRE26685.
 
The plate in the engine compartment said Silver Shadow.  I think the VIN is a 1976.

Make sure this is right for your car.  I do not know anything about Rolls Royce.
 
I have other parts from this car listed and will combine shipping.
