I did a search.. found this old Post, so I have had this one ever since an old Chrysler worker gave it to me decades ago.. must have got it from the car assembly plant, no sentimental value to me.. tab was broken off the back, he stuck a piece of foam on the back (probably from the plant as well..) and said I can use it as a paper clip dish for my desk.. it's just been a knick knack collecting dust, if anyone who has a 72 RR and needs one, let me know..
