The condition of G-ASKK is a credit to the museum management at Norwich, the paintwork still looks quite good.
Other Heralds that were donated to museums fared less well, the ex BAF, ex Channel Express G-BEYF was donated to Bournemouth Airport but was dismantled and scrapped a few years ago.
Ex BIA G-AVPN was operated in her last years as a freighter with Channel Express before being donated to Elvington, I saw some photos recently and she looked rather the worse for wear.
