It really depends on the rarity of the gun, but in general serious collectors (the ones who pay big bucks) would prefer a gun with 10% of the original finish remaining over one that has been reblued if all other factors are equal. A new stock, if matched to the overall appearance of the gun will be marginally acceptable, particularly on a very rare piece, but replacement with an original piece would be preferable. Minor repairs that were made during the period of use will not have much effect on the value if they were done correctly.

Value depends on condition. It makes a huge difference in price when the gun is in 97% or better. Most of the late 1940's guns run $300 to $600 in price. A mint gun could go for $1000+ A professional appraisal is recommended
Value is too difficult to be accurate without seeing the gun. Condition which includes the amount of original finish and original configuration will determine value. Guns with poly-chokes, compensators and recoil pads (other than Mag 12's) will reduce value. Near mint guns and original box will command an extra premium. Recommend taking it to a gun shop for appraisal.
