I am trying to restore an old revelation model 110 from western auto. Previous research has indicated that this is a marlin 81. I have pretty much confirmed this by looking at the schematic on Numrich. The rifle is not tube fed nor does it have a removable magazine. There is no hole in the stock for a magazine nor for a tube. There is a cavity in the stock under the receiver but nothing is there. It seems to me there should be some kind of tray to lay the bullet otherwise I have to put the bullet in the barrel which is quite difficult with my fat fingers and so it usually falls into the cavity. Something is missing but I don't know what. Can anyone help me with what I need and where I might get it?
