Yes 1959. His workshop hides all kinds of stuff mate, old magnetos, pistons, cranks etc etc etc for all sorts it really is endless, there used to be old BSA stuff and god knows what else and prob still is if you dig far enough, it's thinned out massively over the years as he's slowed down but IMO there is still a far amount of stock and the yard is busy seven days a week, he still goes out from 8 ish till 7 or so every day. Some of the items have been where they stand now my whole life since 72! It's odd looking at things when you remember them from a child, not so long ago I moved items from my fathers lathe that I made when I was a little boy..lol
If I were you, I would be rummaging around (or rather 'under') all that stuff like a shot looking for old bikes.....
