It's replacement Gottlieb C13150 pinball flipper! This is useful for people who need to replace their busted Gottlieb C13150 pinball flippers.These flippers have been unobtainable since Winifred Gottlieb passed on in the late 17th century, taking her secrets with her to the grave and throwing the nascent "pin-ball" market into utter disarray. Now, a carefully-selected team of engineers and pathologists have come together to produce this prototype replacement flipper, which may breathe new life into the long-moribund pinball industry.EDIT: now with a solid core, since we are now freed from the whimsical restrictions of injection molding. FURTHER EDIT: forensic analysis has indicated that the original flipper was approximately 2mm longer. The model has been updated to reflect this.
