OWD, check your PM's for a detailed description of the mechanism. Let me know if you don't get it before long. Oh, a little confusing--the Simplex action is quoted in "The British Shotgun" as patent number 1247 of 1875. However, on the action's watertable is stamped "Williams & Powell Patent 531". I'm going to go with the lower number since I believe the gun was made well before the 1875 date.
