A question for those that know. I have a Lee Enfield No 4 which was initially dressed in a Parker Hale Peep sight. Wishing to dress the old lady as she should I was by chance given a set of foresight blades for a Lee Enfield. However, as with most gifts there is a problem. The dovetail on the foresight blade is a shade smaller than the dovetail recess on the foresight block. My question is; are all Lee Enfield foresight blade dovetails manufactured to a broadly similar size, or as I suspect is there a difference for each of the models? Many thanks in advance.
