It is indeed very rare to find one of these dryers still working. They all had an inherent defect in that the fan blade would crack and "throw" a blade into the plastic shroud housing and it would break into bits. I have one of these Philco dryers presently working, but I do believe that most that are still intact had replacement fans and shrouds installed. At least I hope so! I guess time will tell, because I sure intend to use both of the Philco dryers I now have, a lot!
