I have an old Telechron wall clock with a case made of a wood fiber material which is stiffer than cardboard used in boxes, but not a hard and stiff as hardboard such as Masonite. It has a "B" rotor and is slightly noisy. Should I just run it, or try to take it apart to clean and oil it? Has anyone else seen such a clock? In a photo it would look just like any other metal wall clock. I suspect that it dates from the early to middle 1940s.
