I am not sure if anyone has a 30's or 40's Corona portable parts machine, but I am looking for a part for my 39 Corona Sterling. I need the metal piece that sits just behind the vibrator, I think it is called the line indicator (the little black metal piece with the hash marks and the triangular top that frames the typing area and attaches with the two screws.) I believe the part may be the same from mid/late 30's to late 40's Corona portables (Standard/Sterling/Silent). If anybody has this part, let me know.

Below is a picture of the part and the two screws that are undone to remove it.
