I would check that heat treat thing.Folks can argue the fine technical points,comparing with a mauser,etc,but there is just something about the lines and aesthetics of a 1903 or A-3,along with the history,trips my trigger.
Others are entitled to their opinion,but so long as the receiver is of a sound heat treat series,and nothing horrible has happened to it(like drilled and tapped for side mounts with a hand drill,a couple extra holes,none in line,size 1/4-20) any Springfield receiver is a prize.(please PM me if you have a good one you want to get rid of cheap)
Some folks get their boxers all wedged up if they see anything but original condition,I don't care.
Back in the day,Redfield was considered a premium scope,and Weaver the standard.A fixed 4 x was as standard as a 3 to 9 x is today.It was the standard hunting scope.
If the stock is premium wood,if the grain is laid out well,and if you have enough wood to shape to something elegant(old home sporters are often clubby,with extra wood) the stock may be a real bonus.
Try buying a nice,hard,fine grained,slow growth piece of American walnut,with a proper grain layout and some figure.If you can find it,have a few $100 Dollar bills with you.Now you have a board and some work to do.
If you want to make a sleeper out of it,Criterion/Kreiger sells replacement original contour 1903 barrels.
Is it a steal? Probably not,but if nothing is messed up,you may be able to have an exceptional rifle out of it .
BTW,your safety may be a Buheler or similar lo-swing,designed to only swing part way,to clear a scope.
