Don't have any pictures of what you are asking, but I did want to say Anson and Deeley forends are two different designs. The Anson forend is a pushrod(anson pushrod_, where the Deeley is a latch inletted into the forend wood(deeley latch). The names aren't used together when describing a forend, only when describing the common boxlock action.
