John Haining – many thanks David at least for giving my suggestion some consideration. As you know, he was the author of two books, both of which are still available from Amazon, although, I don’t know who the publishers are. They would have contact details if only to pay royalties to the estate.
Edward George (Martin Wallis) has also written a book about scale model traction engine construcyion and, as far as I can see, has more knowledge than virtually anyone else in this field, that knowledge might well extend to knowing the whereabouts of the Haining family.
The index for volume 194 – January to July 2005 has an entry for John Haining’s obituary (pages 309 & 369) ; there may well be clues there. As this is only four years ago his widow may well be still alive and might be all too pleased to give the necessary permissions in memory of her late husband.
I did try
http://www.192.com but the surname is not sufficiently rare to make sense of the entries.
Thank you for your efforts.
