The dial escutcheon is fine as it is, I had one on a Philco 120 that someone had shined up and it never looked right to me, so I painted it black once I found out that they were originally darkly finished. I don't know if the dark finish was lacquer or some sort of chemical treatment like gun bluing, but shined up escutcheons are for shill scam artists on fleabay, not restorations. As for the glass I think that Radiodaze repros those now, one the 620 the glass was silvered like a mirror in places, I don't know about the 610, so I doubt if Radiodaze silvers them like the originals.
