In open storage at Johnson County Airport, still fitted with agricultural spray bars. Joined the US Navy in 1945 as BuNo 37472. Became N5223V in 1957. Re-registered N7670C in 1963, operating as a sprayer initially based in Arizona. Bought by Hirth Air Tankers in 1987. Conversion it to a firebomber was not followed through before John W. Hirth tragically died while firebombing and ownership passed to his wife in 1997. Sold at auction in 2005. Fitted with an upper turret and restored to flight in US Navy Aleutian Campaign markings as 37472 "Attu Warrior".

With the Vintage Aviation Museum in Utah by 2016.

This was not a sprayer like the other Harpoons stored at Buffalo, but a fire bomber with appropriate Tanker number.

In this photo this Harpoon is still fitted out as an agricultural sprayer, with spray bars on the wings, but those wouldn't last much longer. A few months later it was sold to Dave Hansen (Warbird Aircraft Sales) and restored to flying condition in US Navy markings as the "Attu Warrior". It was flown to its new home in Heber City, UT on 9 Oct 2007. The aircraft was still proudly flying by August 2015, but was withdrawn from use shortly thereafter, when Dave Hansen was diagnosed with cancer. He passed away in January 2018.

Seen here still fitted out as an agricultural sprayer, with spray bars on the wings. This Harpoon remained stored at Buffalo for another decade before being sold in Oct 2016. Restoration work reportedly started in late 2017 by Sean O'Brien's Vintage Aviation Museum. The plan was to have the aircraft flying again by summer of 2019.

By 1995 this Hirth Air Tanker Harpoon was being converted to airtanker, but the work was abandoned after the owner John Hirth died in the crash of one of his PV-2 Harpoons on 20 Apr 1997. It was left stored here, with engines and other parts missing. Remnants of the registration are still visible on the fuselage. In early 2007, Gary Hilton acquired this Harpoon with the intention of moving it to his hometown of Lone Jack, MO. By 2009, he had gotten as far as removing the wings and nose (and possibly moving them to Lone Jack), but then his plans seem to have stalled, as the aircraft was still at Buffalo as of 2020. By 2023, it had been moved into the front yard of a house just southeast of the airport, still without its wings and nose.

Ex-Hirth firebomber, this classic aircraft was in surprisingly good condition
