Very nice. Thanks for sharing that with us.
I had a situation here in Oz where a fellow collector passed away. His family had no interest in his collection and no idea who Bert Hinkler et al were and the collection went to the tip. My own collection will hopefully go to friends who appreciate it. My family have no interest in Aerospace History.
