Well maybe. But the airplane I flew in was a 580 and when you look in Convair 580 in FSM, there it appeared. Now maybe it was a transition to the 600 series. They seemed use everybody's cast offs.
Like I said, when peeling off the stickers on the seat belt, the airplane had banged on a lot of runways. I used to ride Mohawk to Buffalo from Boston. It took six landings and and take offs before you got there. Each one a new adventure.
