Cpt Curl,

My pleasure. I think the old W W Greener book The Gun and its Development details all the English actions very carefully. I contacted the Greener company because I still remember an old Greener shotgun that a friend's father had in India many years ago. It was one of the most beautiful guns that I have seen. He sold it when his father died and moved to Australia like many Anglo-Indian families did in the 80s. I wish I had the money to buy it then!
