Need help identifying the year of manufacture and possible value of an 03A3

[PeteDavis]

That bolt is 1903 Springfield and is nickel steel, from the 1930's. One gas hole earlier, two gas holes later.
That rifle has been stripped of original finish and reblued, dulited or painted. If it is a DP rifle you will see the remains of grinding around the cutoff area (on-off switch) where welds were applied. Parkerizing does not take to the hardened weld areas which could explain the finish. Show us a pic of the cutoff, and take it from the stock and show us a pic of the underside of the chamber swell. That area would have been tacked as well.
Someone tricked it the rifle for sale or target work and it appears they did a nice job. If it is an old DP it won't have a high value-but lack of original finish does the same thing anyway, just to a lesser degree.
