Welcome to the Forum DIRLLIGAF
I have never seen a Nickled 15-2 In person & have seen several 715s that were stainless
Is it Possible that the one you used to own was Nickeled by a plater & not a Factory Offeing?
I Like a Fool sold of My early DW 15-2 & just aquired another, Not quite as old, But I've done a triigerjob on it & got it as Slick & Smooth as they Come..
Good Luck Finding One to replace the one you Let Go..
