Just found news of a replica DH4 built by Century Aviation for TVAL. Century Aviation are based at Pangborn Memorial Airport, East Wenatchee, Washington, US
"We have just completed a replica of the Airco DH.4 for The Vintage Aviator Limited (a flying Museum) in New Zealand. They will use a Liberty V-12 engine on which they are doing the overhaul. They will have the instruments certified, install the fabric and paint the wings and tail surfaces. They are also supplying the propeller, wheels and tires. When their work is complete, this DH.4 will be flyable."
