You're looking at a small "niche" group when it comes to such rifles.
At one time there was a lot of interest in that concept, but there were also a lot more competitive shooters, most of which have passed away.
Most milsurp folks love fondling these beauties but aren't willing to pay for them.
As far as refinishing, when it comes to this type of set up, it's worth what the market will bear at any given moment, region, and of courses circumstances.
Some clubs have very active milsurp shooting competitions and they usually have "classifications" with parameters. Most are "flexible" but they can be limited to models such as the No1 MkIII standard issue rifle and as in your case a rifle which may have been cherry picked for accuracy, tuned trigger, and stock fitted to the shooter.
Anyone interested in it may want it as a parts rifle or a "gap" filler in their collection, or a shooter, but if they want it as a shooter, they will be concerned with such things as "ways bedding" trigger set up, headspace and throat erosion.
I've seen similar rifles, looking like they were new out of the crate, with the throats eroded six inches. All of the above will indicate the real value of what you have.
If the throat is eroded beyond the point good accuracy is available, then you might be better off tearing it down and selling it for its component parts.
The stock should be worth $500. Magazine $65, Trigger Guard $25, Trigger group, including spring and pins $25. Bolt $75, Barreled receiver $75-$100 depending on wear, Stock ferrules, sling swivels, screws, and nose cap$200, and another $30 for the butt plate and screws, Match sight $300+
That bayonet broad arrow stamp isn't questionable at all, it's fake. so $100 if it hasn't been sanded wire brushed, depending on who made it.
Selling it as a complete rifle will not bring as much as selling it for parts, but then you have to put a lot more effort into it.
