John Lennon 1

Hi All, I am very new to this. I have a Hi boy precedent I built with my father many years ago. He has now passed so I can't pick his brains on what's what but I am very keen to renovate my hi boy and join a club to start flying her. Does anyone have a copy of the build instructions, operating manual and any suggestions on who I can contact in the UK for parts? Many thanks in advance. John
