What were the original rubber ring colors?
As far as I know, the rings were white the flipper rubbers were black and the rubber sleeves were black except for the two at the captive ball which the manual calls for 2 yellow sleeves. The original flipper-bats (plastic part of flippers) were white, however I’ve seen IJ’s with yellow bats installed by technicians and the yellow flipper bats don’t look too bad in the IJ with the yellow-orange color scheme they fit right in.
