I'm afraid I'm going to be the dissenter, here.
Unless it's the lighting, the stummels' color looks blotchy, which is definitely not what the Bruyere finish looked like at any time. (The shade morphed from a deep plum to a more reddish tone over the decades, but the color saturation/intensity/whatever-you-want-to-call-it has always been even and consistent).
Did you polish them on a 3600 rpm jeweler's buffer? (one of those shoebox-sized machines where the shaft comes to a threaded point on each end) If so, that would cause the color mottling.
Also, their glassy appearance looks both odd and historically wrong. If that's just shined wax and a heavy hand on the "clarity" edit function when you processed the photos, never mind. If it if some sort of glossy clear coat add-on finish, though, I would strongly recommend you stop using it on historically significant collectibles.
