On the subject of extended trigger guard tangs one English straight hand stocks, I was always led to believe that it was done to add some support to the wrist of the stock.
But there is always an exception to what we may think, in the two photographs is a stock from a Samuel Ebrall 12 Bore Pin fire support is also given to the wrist by the Action top strap. I have only seen a couple of guns with what I have known as a Rat Tail top strap but there may be a more up market name for it, the idea of supporting the guns stock looks on the face of it good. But it seems to fall down if you want to adjust the stocks cast that is if you could find a Gun Smith to do the work.
