There is a Gentleman here in Maine, who has the most Wonderful William Cashmoore 12b DB Anson/Deeley Action.I've done a small repair to it,stripped it down completly checked all the 'Important bits". I would not hesitate to say it is 'The Best!. The History that is with the Gun, from Mr Cashmoore building it and presenting it to the winner of tha Grand American Handicap..I think it was 1900.I also think it has 3.1/2" chambers, I will go to my 'Unorganized File" Shelf under the Bench, I have a file with tha Owners pho.#. This really is a Birmingham built Pigeon Gun that is a gun worth 'Seeing' C/C
