Wrays has nothing to do with Procter, although I see he does have a dormant company registered in that name. It is part of York Pullman, owned by Tom James, which you'll see as the registered legal address on the side of the coach.
York Pullman also operate other businesses around the area including Dodsworths at Boroughbridge and Ideal Motor Services at Market Weighton.

The proper cowboy operating around the North has just gone out of business and this is indeed the very thread....
