Remington 1903. 30-06 above.
Adjustable ring sight at the rear.
Maybe a WW2 war barrel with shorter aftermarket stock put on later on. IDK.
It says Remington, but from what I understand all the war rifles were Springfields.
And I've read that Springfield Arms of today is not associated (in any way whatsoever) with the original Civil War-WW2 company.
Winchester Model 61 .22LR pump below.
Some internet pics have the scope further forward.
