Hmmmmmmmm... Stainless didn't come out till the next year, but it could be nickel. The bottom of the sight insert isn't square so it don't look milled. Stocks are poorly fitted. Shroud has no emblem and is made of cast metal that's not even polished to match the revolver. This is suppose to be a Colt Custom Shop model?
At best, it could be one of the bobbed hammer hard chrome dot night sight custom 4th issue DSs with the shroud butchered on (why put a shroud on a bobbed hammer?), a DIY insert and some Secret Service grips, but it certainly doesn't look well done over all. /forums/images/graemlins/crazy.gif
