Description:Up for sale is a historic piece of Connecticut aviation history: a vintage Helios 6-inch precision dial caliper presented as an internal service or presentation instrument to employee/machinist within Pratt & Whitney's Department 97 (D-97). Featuring official "Western Germany" factory stamps, this precision tool definitively predates the 1990 German reunification. It stands as a well-preserved artifact pairing top-tier European metrology with Cold War-era American aerospace manufacturing heritage.Specifications:Brand: HeliosManufacturing Origin: West Germany (Pre-1990 Reification Era)Provenance: Officially assigned to Department 97 (D-97) of Pratt & Whitney, ConnecticutMeasurement Range: 0 to 6 Inches (Graduations to .001")Markings: Hand-engraved to an employee with their ID number "162540" and department "D-97" on the slider casingConstruction: Hardened stainless steel with satin-finish imperial scale beamOriginal black textured hardshell protective storage case with fitted plush red velvet-lined interior and nameplate sticker matching the employee F. M. LastCondition:The item is in used condition. The instrument chassis and jaw alignments remain structurally intact, showing a bright satin-finish metal beam alongside minor surface scuffing, micro-scratching, and light storage patina. The analog dial window is clear and readable, showing standard superficial hairline swirling with minor debris beneath. The hand-engraved corporate provenance text on the slider housing is clean and perfectly legible. The velvet-lined interior lining is solid, showing typical age fading and slight tool nesting marks. The external hardshell casing securely latches and displays expected fine scratching and edge wear from historical hangar storage. Internal calibration accuracy, mechanical tolerance specs, and fine gear alignment are untested. This aerospace collectible ensemble is sold as-is.--These items are part of an estate from a collector and carpenter by trade (descended from other crafts-persons, mostly in Connecticut). Payment required within 48 hours of auction's end. All items from a smoke-free environment. Please check out the other items from this collection!
