I've recently acquired a Singer 66-16 in a cabinet. {

Day before yesterday I was cleaning the surface with oil and cotton balls and had the slide plate extended.
I got distracted and forgot to close the slide plate when I rotated the machine into the cabinet. When the plate hit the top of the cabinet it popped off the machine with a resounding "PING". I looked at it and thought ..... I wonder if that is why so many machines are missing their slide plates?
Just a thought.
