Description
GRUMMAN G-73 MALLARD Complete Restoration • New-Build Center Section • Exceptional Condition An extraordinary opportunity to acquire what may well be one of the finest Grumman G-73 Mallards in existence. This exceptional Mallard underwent a comprehensive restoration by Victoria Air Maintenance in British Columbia, Canada, with meticulous attention devoted to both structural integrity and overall presentation. Of particular significance, the aircraft received a completely new-build center section as part of the restoration—an important distinction for any serious Mallard buyer. Since completion of the restoration, the aircraft has never been operated in salt water, helping preserve the airframe and protect the substantial investment represented by its restoration. The result is an exceptionally well-presented example of Grumman’s legendary amphibian—an aircraft combining timeless design, remarkable capability, and increasingly rare collector appeal. For the buyer seeking a truly outstanding Mallard rather than simply another aircraft on the market, this example deserves serious consideration. Highlights Comprehensive restoration by Victoria Air Maintenance Brand-new center section constructed during restoration No salt-water operation since restoration Exceptional structural and cosmetic condition Highly desirable Grumman amphibian Maintained to an exceptional standard Possibly the finest Mallard available anywhere
