Antique Automobile Dash Mounted Stem Wind Clock

Description

Seems in good condition, if you wind it and tap the case it works but probably could use a cleaning, the covering is a celluloid dome and it is discolored - not sure if it can be cleaned or if it needs to be replaced, I cannot find any makers name on it,  case is (guessing) nickle plated brass, external dash mount, mounting holes (side to side) about 2 5/8 apart - in the center top is a third hole centered between the other two, email if any questions or more info needed
