Hello, all, especially those with familiarity with subject. I've got a
decades-old Stromberg-Carlson SC-2554 wall mount phone. It's still in
great shape except recently a small white piece of plastic on the
make/break hook switch broke rendering the rest of the cradle mechanism
inoperative. The plastic piece finally broke from the tension from the
return spring. It's a clean break but I'm afraid that even if I can
glue the pieces back together it will most likely fail again in short
order. Thanks for your time and your comment is most appreciated.
Sincerely,

Mpfffff... take out the part. Put it back together with JB Weld - available everywhere. Be sloppy with the material, but make sure that you do not glue the part to anything else. I will on occasion tie such a part together with fine thread (if there are holes through it, even better) and suspend it during the curing process. Then with files, X-Acto and sandpaper, reshape the part to its correct size, removing flash and sprue, so to write. Re-drill any filled holes and you are done. JB Weld will be harder and stronger than the OEM plastic by a considerable margin.
