I know you're a bit of a Scott fanboi, and I have a Scott or two in my cabinet too, but they built guns of many grades, quite a few better than this, and there were better makers.
You and I can both see the difference in condition, but you can not discern a difference in quality? On the Scott, I can see file marks all over the face where the breech hooks in. I can see a difference in coverage and fineness of engraving.
To answer your questions: the platinum plugs in mine are vented. As to hammers: on mine, one is a replacement, but both are designed not to vent, but shaped "out of round" (actually, they're not, just a perspective thing with a mismatched hammer, but whatevs...) to closely enclose the nipples. Not sure how common that was; it might be a fashion, or an era, or peculiar to that maker...
