These B&S Tapered Parallel set is in excellent condition. This set has a calibration sticker indicating these parallels were in the Airesearch calibration program. Garret Airesearch made superchargers for the US WWII aircraft along with the supercharger for Oldsmobile in the Turbo-Rocket V8, which was a groundbreaking engine introduced in the 1962 Oldsmobile Jetfire. Parallels arrived in excellent as described condition. These were like new, yet older than me. Pricing was a very excellent.
