This Bronco previously served with the US Marines as Bu155401.

Withdrawn from use in 2001/2002 and stored here with some parts missing and the registration painted out.

Withdrawn from use in 2003, and sold to Chris Schneider in 2006. It was still stored in the exact same place by 2018. This Tracker previously carried tanker numbers 73 and 74.

This Tracker airtanker was withdrawn from use circa 2005, and bought by Chris Schneider in 2006. It was still stored in the exact same place by 2018. This aircraft flew as Tanker 75 since 1974, but by 2004 it had become Tanker 77.

This splendid-looking CDF Huey once served with the US Army as 69-15713.

Tanker 83 is the third Tracker to use the registration N424DF. The first one was c/n 254 (1974-1985) and the second one was c/n 403 (1985-1998). The Tracker in this photo was registered as N424DF on 30 Aug 2001.

This immaculate Tracker is the very first Marsh Turbo Tracker. It was converted in 1998, and registered to the CDF as N422DF on 30 Aug 2001. It is the third Tracker to use that registration. The first one was c/n 017 (1974-1985) and the second one was c/n 212 (1985-1998).

After more than 30 years of faithful firefighting service (9,952 flying hours), the CDF transferred this nice little airtanker to the Columbia Airport Authorities on 7 Apr 2006, for display at their airport. Tanker 76 is located on the remote side of the runway, hence this distant and somewhat heat-hazed shot.

Nice elevated view from the control tower, with Tracker N435DF parked behind.

Elevated view from the control tower. This is the second Tracker to carry this registration. The first one was c/n 410 (1974-1985), but it never saw active service as such. On 1 Feb 2000 the registration was allocated to the this Tracker.

This unknown Huey has been a ground trainer at the Hemet-Ryan airtanker base since about 2002-2003. It is widely quoted as UH-1F N490DF (c/n 7108), or as UH-1H N490DF (c/n 12375), but it is neither. It has a long cabin (i.e. a UH-1D or UH-1H), so the short-cabin UH-1F c/n 7108 can be ruled out. And UH-1H N490DF was still operational with Cal Fire by 2018, as Tanker 205.
So the only known facts are that in 2003 this ground trainer still carried "Vina Helitack" titles, and tanker number 205. The long cabin means it must be a UH-1D or most likely a UH-1H. And it operated as "Copter 205" for the Vina Helitack before 2003. Suggestions most welcome!
