Sorry to hear about Tony.
I bought a copy of his book not too long ago. We exchanged quite a few messages through Facebook and he asked me what my interests were. When I told him my main interest was the history of Merseyside railways and I was planning a model of the LOR, he sent me 6 DVD's that he'd made of railways on Merseyside, free of charge. He even messaged me a month or so after he'd sent the book and DVD's to ask me how my project was going. A lovely, kind man and I would have liked to meet him in person, but glad our paths crossed in a small way.
R.I.P. Tony.
