{"product_id":"original-1964-turbine-engineering-drawing-hand-drawn-technical-industrial-art","title":"Original 1964 Turbine Engineering Drawing Hand Drawn Technical Industrial Art","description":"Fascinating original hand-drawn technical rendering depicting a sectional view of a turbine assembly, dated August 11, 1964.\u003cbr\u003e\u003cbr\u003eExecuted in graphite with handwritten engineering annotations, the detailed drawing shows the internal components, turbine\/compressor wheels, ducting and mechanical housing of the proposed assembly. Handwritten notations include “2nd Proposed” in two locations, along with additional project notation at the upper right and what appears to be a draftsman’s initials or signature beside the date.\u003cbr\u003e\u003cbr\u003eThis appears to be an original working technical or conceptual drawing rather than a commercially produced print. The specific manufacturer, project and draftsman have not been identified, and no attribution is being made.\u003cbr\u003e\u003cbr\u003eFramed dimensions are approximately 11 inches high × 8½ inches wide.\u003cbr\u003e\u003cbr\u003eThe drawing shows age-related toning, light staining, handling marks and other wear consistent with a working document dating to 1964. Please review photographs closely for condition and all visible annotations.\u003cbr\u003e\u003cbr\u003eAn especially interesting piece of mid-century industrial history and a fantastic display piece for an engineer, machinist, mechanic, turbine or aviation enthusiast, industrial designer, or collector of technical drawings and vintage engineering ephemera.","brand":"Heritage Haven Antiques","offers":[{"title":"Default Title","offer_id":67937023066311,"sku":null,"price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0671\/1512\/2887\/files\/7ddd2521-4961-41bc-bf4c-d1b47edeef57.jpg?v=1792206951","url":"https:\/\/shopheritagehaven.com\/products\/original-1964-turbine-engineering-drawing-hand-drawn-technical-industrial-art","provider":"Heritage Haven Antiques","version":"1.0","type":"link"}
