Large Standard Steel Propeller Co. 20 Ln. Display/sample Propeller Nr Mint For SaleThis is a rare large size ( 20 in.) replica of the Standard Steel Propeller Co. of Pittsburgh, PA prop used by Charles Lindbergh on the Spirit of St. Louis. The Hamilton & Standard propeller companies merged in late 1929. While I'm not sure exactly when this propeller was produced it probable that it was done for the 50th anniversary of Lindbergh's flight to Paris, 1977. United Aircraft, the parent company of Hamilton-Standard was merged into United Technologies during 1975. There were many smaller versions ( 10 in. ) letter opener sized versions given out as advertising pieces over the years. In fact I'll be listing one of those in the original box after I complete this listing! This prop includes a 5 in long hub bolt with integrated spinner. I have an old friend who is a retired United Aircraft tech rep who has had many different size and styles of these Ham/Stan props over the years. He said he'd only seen two of these over the years and they'd been mounted in UA offices on plaques. I just bought this one from the estate of an old-time collector who bought it over 20 yrs. ago at a flea market in the Hartford area, not far from the UA/UT offices. This was most likely removed during one of the several moves these offices experienced in the last 30 yrs. This 20 in. prop & hub bolt weighs 2 lbs. and is in mint condition! This would be a great prop for a large scale model of the Spirit of St. Louis!
