The set should have 14 but only 13 are included. It looks like a common piece.
I have ordered ten (10) of part F the 5 hole perforated strips. The motor has been tested and works fine, this set includes 2 red bulbs, only one was in the original set so there is a bonus one. These worked when we tested them. Many of the screws are still on some of the parts, but they are there.I didn't want to accidentally unscrew anything that was not supposed to be unscrewed so I just left them where they were. Metal box is solid and in good condition. No major areas of rust - see photos. Clips still works well and hold in place. I will include additional blank inventory sheets.
