Do what YOU want to do to Your rifle. If it was a rare model I would tend agree with previous post. I have a big collection of Military guns and personally if gun is all original I leave it that way. Why? Because they are mine and that is what I choose to do. I will build a sporterized rifle as long as it is not one that is complete and matching. That being said though, if it is a typical WWII dated model, dont worry the world wont miss it. If anybody complains see if they are willing to give you what you paid for it so they can put it in their own Musuem.
This attitude is why vintage military guns are so valuable; the Finnish Mosin that went begging for $40-50 15 years ago is now worth $400-500, the lowly Turkish Mauser that within the last 10 years only cost $30 now runs $200+, and I could go on. Mark my words: in 5 years a "non-matching" 91/30 will be a $250+ piece. Don't say nobody tried to tell you.
