NuTone Vintage Door Chime Picture Gallery > NuTone LB42 Westminster 8 Note Chime > nuTone LB42 plungers and springs

Here are the 4 plungers and the 4 return springs.  Be sure not to lose the springs when the plungers are removed.  They are necessary to make the chime ring correctly and of course they are no longer available.

You can see the black gunk onthe end of the plungers (blue arrows) this is whatreamins of the foam cushion that was originally inside the soleniod tube. 

Since this is a mid-70's chime, the cushion was made from a cellular foam material, which was probably dissolved  when someone spray WD40 into the solenoids.
