Vintage Teledyne IVSI Vertical Speed Indicator - Boeing 727 (Ex-Qatar Airways)

Item description from the seller

For parts or not working. "Listed as 'For parts' as I am not an FAA-certified technician and cannot certify airworthiness. However, the unit is in excellent cosmetic condition with a crystal-clear faceplate. The needle is highly responsive and moves freely when handled/tilted, confirming internal linkages are intact. Features an original 'Functional Test' sticker dated January 10, 1986." Detailed Item Description Aviation History & Provenance: This is a genuine Teledyne IVSI (Inertial-Lead Vertical Speed Indicator) salvaged from a retired Qatar Airways Boeing 727-200 Advanced. This specific unit (Serial No. JD1050E) represents a premium piece of 20th-century aviation hardware from an airline that began its storied history with the 727 fleet. It was acquired at the Av-Con 2026 event at the Delta Flight Museum in Atlanta. Technical Highlights: This is the advanced Inertial-Lead version of the VSI. Unlike standard pressure-driven indicators that suffer from "lag," the IVSI incorporates internal accelerometers to provide the pilot with an instantaneous vertical speed reading. This was a critical high-end feature for commercial jetliners of the era. Condition Report: Visual: Faceplate is crisp with high-contrast markings. The housing is solid and shows minimal wear consistent with its service life. Mechanical: Needle shows excellent movement when the unit is tilted, indicating the internal inertial weights are free. Verification: Includes the original Teledyne Charlottesville, VA data plate and the historic 1986 Functional Test sticker. Rear Ports: Pneumatic ports are currently protected by original pink caps to ensure no debris enters the sensitive internal diaphragm. Ideal For: Flight Simulator Builders: An authentic centerpiece for any Boeing 727, 737, or 707 "Classic" co
