I've run across threads from time to time which mention the discovery of a tin of kerosene and a feather in the bottom of a clock case. So many jokes were made of this that I didn't take it seriously or I thought that it must not have been a wide practice. After about 9 years collecting and working on clocks I've finally run across one. The pictured Seth Thomas No. 89 had the tip of a feather stuck to the inside surface of the front plate. I must say that I'm not overly impressed with the end results. Perhaps the person who lost part of their applicator feather just had not quite mastered the technique. From the looks of the badly scored pivots, gunk and stains throughout the movement it looks like the service tech got the kerosene everywhere except where it might do some temporary good. Fortunately fresh kerosene on an old toothbrush helps to remove the tenacious dirt, residual kerosene (?) and debris. My Ultrasonic Clock Cleaning Solution left a lot behind. I'll be placing a lot of bushings (and at least one on the Time Side Great Wheel shielded by the cup bell), once I refinish all of the deeply scored pivots. So, before there were aerosol "lubricants" like WD-40 et al.,there was kerosene and chicken feathers.
