Quoted from pinkid:
I just got some of the short lane dividers with the Bally logo on them for my Bally Playboy. I had replaced them with some plain generic ones, but will install these soon for more of a "factory" look. Planetary pinball has them in white and red. Got some red ones too for my Strikes and Spares, Mata Hari and Fireball II. I haven't seen these available for a long time.
Dude great freak’n find. I’ve been looking for another set of these forever. Had some older ones my buddy hooked me up with when he restored my playboy. They were a bit yellowed but I did the hydrogen peroxide and sunlight for 4 days and it really whitened then up. A back up set is key though. So hard to come by.
