As you said there are not many nice 03's around. If you like it snap her up and find the parts if you can to make it like it just came out of the factory or know that it has been used and been many places. Parts are changed and updated. To say it makes it less valuable than a stock untouched one is folly in my opinion. I had a Winchester M1icon Garand from DCM it had many different parts on it and I was able to find the "Right" parts and put her back together....was it any better? No. It was fun and I did meet a lot of nice people at gun shows and on the internet.

So it's just a matter of perspective in my opinion. There are those who would leave it alone because it has a story to tell.
