Hi Jim,
Sorry to have to get in touch with you this way, I am Richard Maynard, David's brother. Just a quick note to thank you for the obituaries you have posted regarding the sad death of my brother - to say we are overwhelmed by the responses would be an understatement, and it is difficult to read the comments without a catch in the throat and tears welling in the eyes. We all would like to thank those who have posted their remembrances of David. I have considered registering myself on all the sites we can find his footprints on, but I last modelled many years ago (probably could not compete with David), and don't know if an account for this purpose would be a waste of server space... We know about him on Armorama, Military Modelling, missing lynx and airfix, any others gratefully appreciated, along with what his user name was and contact details for any relevant mods.
Regarding his accounts, we would like his posts to stand in case they can help others in the future, and new people can find the remarkable human being who was my brother
