I did give that second pastern gun at Bonhams a closer look. It has been re stocked and not a very good job of it. The wood quality is a little lacking No drop points, plus the head section is a little narrow because the pins are protruding from the lock plate. It also may have had a replacement main spring in the lock showing because the spring positioning stud is rather to large.And that but plate the less said the better, it could make a nice project if the barrels are OK because the price was good.
Just for some fun the photograph is a card made by my eldest son to send to friends, inside was written "For the man who has everything" you will receive them tomorrow. On the rear of the card was "tomorrow never comes." They are two of the hardest to get man toys.
