Quoted from snakesnsparklers:This mystery plastic piece came off during a game the other night. I first saw it towards the center of the playfield then it slid down towards the flippers. I looked over the PF and couldn't find where it came from. I'm sure it doesn't matter that much but I'm curious now. Anybody have an idea what it's from? It's maybe 1/4" wide
That looks like the tab that curls under at the base of the gas pump.
