Appear smoother & brighter than some I've owned. Many of mine were sort of a matte black with some a matte blue and some gray and some obviously reblued. Had a 99%+ 243 SG FW, its swivels were a matte blue-black, obviously unpolished before bluing but still fairly smooth.

These, to me, are the ultimate in snap swivels for the prewar-style rifle and indeed for almost any custom retro Winchester of any era.
