Another DH106 Mk4C has been under restoration at the Museum of Flight restoration center in Everett, WA since 1995. I don't think that a single thing has been done to it since the outbreak of the pandemic in 2019. Allegedly they will be losing their lease in few years, no idea if they will do anything to complete the restoration before then.
