They are called the Masterpiece for a good reason.
I bought my 14-4 about 7-8 years ago. At the time shooter grade guns were selling for $250, I paid $350 for a NIB specimen, I have shot many thousands of rounds out of that gun and it is now probably in about 90-95% condition. I see them in about the same condition as mine now for $4-450 with NIB priced for $5-600, I don't know if they are actually selling at that price. I love my Model 14 so much you are going to have to make a very high offer for me to even consider selling it, it's just the perfect gun for me, and every little rub mark ding and scratch is mine, and I can tell you how it got there. So at the time I thought I paid too much for my 14, but now I look at it as, I just bought it too soon. Even if $500 is a little too much, 5 years from now you will not even care about that extra $50-100, and a NEW Classic 14 from the factory is $800 with the added hole in the side.
