Stan, yes they are very uncommom and especially in the options you have. Lools like a decent piece of wood for a Field Grade also.
Under the for-end does your have a piece of metal shaped into a U between the barrel's for-end hanger (loop) and to where the barrels are joined at the water table? They call it a re-inforced splinter.
It is there to take the load off the for-end loop from coming loose when doing a lot of heavy shooting.
