Picked this up a few weeks a ago. SN makes is a 1995 Gold Cup National Match. But... I have another 70 series GCNM, and it has a NM slide, NM barrel, and target sights. Did they change slides to what’s on here now for the 80 series, or ones made in the 90s? Figured I’d ask the MSGO experts on this one. Also, if it ends up on the sale page, what would be a good and fair asking price? Thanks for any info you can give.
