Some of you may know that I collect railway paperwork, including timetables and train orders. I recently became aware of train-orders.com, run by the redoubtable Ken Secrest. I've purchased a number of train orders from him on eBay and he has been excellent in every transaction. So, if you are looking for train orders, he has listed a number of them on his web site. Check them out!
EDIT: Gary Scott tells me the operator was Donnie Hillman. Ray Furlong was another operator at South Devon.
