Biggest Durham knocker collection?

In the process of improving our Durham B&B I seem to have acquired an awful lot of Durham sanctuary knocker related articles - everything from pottery goblets,jugs in all sizes (knockers on jugs, oh dear) actual door knockers, letter opener, plates, toasting fork, shoe horn, thimble, letter rack, pictures, mostly pottery and brass, so theres 'knockers everywhere you look' along with 'Ringtons in every room' to really let you know you're in the North east.  havent got the t shirt yet mind, its mostly confined to decoration thank goodness.
