GM Diesel Power vintage watch fob

Up for auction is a GM Diesel Power watch fob. I have no idea how old this is, it came from my father-in-law's estate. But it has a phone number on it, Hickory 3-6541, it has been a long time since phone numbers started with a word. Check out the pictures and decide for yourself. Ask questions before bidding. I only ship to continental US. I do combine items to save on shipping, but I do not like to hold items for more than ten days. WAIT FOR AN INVOICE FOR COMBINED SHIPPING OR REQUEST ONE. Please check out my other items for sale. If you are looking for something in particular, just ask, I'm selling my entire collection and then some.
