The Photo of a Beesley Self Opener"In the White" That I have been Building for Many Years, Is the only "Purdey Type" Gun thatI know of that has a Churchill Repeating Double /Single Trigger(See Don Masters Book,"The House of Churchill, Page 173 for the Pat. drawing that we copied and I installed into my Gun.)I know why I have never seen another of this type of trigger set into a Purdey S/O! ..Will ask Rev Doc if he will post a photo of the "Home-Made" Trigger Mechanisim. I have Shot the gun, and It seems to work"Quite"Well..Way too much work to be "Practial: Next Photo will be of the Mechanisim....CC/dt
