Maybe 1969, certainly not 1959. Not really expensive though, as there are several pieces of rolling stock and the relatively rare M7 plus a diesel (appears to be the class 31). At £3 each for the "carriages and carts" , £10 for the diesel and £20 for the M7, we are about at his starting price. However seeing it's been relisted, it would appear not to be in great demand.
