As far as the original customization, I was told that the gun was customized by New England Custom Gun Service. I personally don't know anything about them, so not sure if they are known for quality or not. I don't claim to be as knowledgeable as most of you on here, but I do tend to gravitate towards the pre64 custom Model 70's (I have a few Biesens, etc.), and this one seems have been done very well.
