Thank you all for the great information. I assume the comment about the drop in the stock vis-a-vis Seagirt was directed toward using the rifle in the back position. I obviously have no evidence that the rifle was used at Seagirt, but the only evidence of the rifle ever having a rear sight are the filled screw holes on the heel of the stock. I can't think of any way to use a sight on the heel except in the back position. As an aside, I can't think of a more uncomfortable way to shoot a rifle than from the back position, stock drop or not.
Regarding the identification of the rifle as a Hi-Power. Is Hi-Power a sub-model of the No 3 designation or part of a separate model line?
With respect to a rear sight, did Remington make their own tang sights or were they purchased from another company such as Lyman and then Remington marked? I have a Lyman tang sight coming in that was removed from a Hepburn because the owner installed a taller sight with windage adjustment for use in BPCR competition. I'll use that sight to get the rifle running again and pursure authenticity in the future.
Incidentally, the bore is as perfect as I can see with the naked eye. Someone took good care of the old girl. The man from whom I purchased the rifle owned it twenty-five years and never shot it.
