    If you look inside the reciever ,you can see the cast surface....the cast reciever is also cored out in places where the forged one is solid....I would think a genuine 40/85 would be a forged reciever......and it wasnt just the early ones were cast.

    Very few,virtually none of the Mk 1V s were converted to 303.......looks to me like someone bought them to practice engraving on......For conversion to HP rounds,a 303 would save you the work of bushing the block and reducing the firing pin dia.

    The catch with hammer pivoting in the frame is that the action needs a fair bit of drop to get the hammer out of the way.This is the big sale point of the highwall,the hammer disappears for loading...I personally prefer a side hammer with a back...
