Helen:-
just had a look in my old Manx programmes. 1977 ( the last year Roy seems to have ridden)it says :-Garnett,Roy,29, single.A rigger from The Wirral, Merseyside.First entered the MGP in 1970. Club, Nantwich. He was entered in the Lt/ wt race, no 79 on a 180 Honda (a bored out CR93)And according to the 1978 programme he didnt finish.Lee Heeson comes from that neck of the woods and I sometimes see Lee at Darley Moor (he's a scrutineer now)so Ill ask him for you.
