Does the standing rear bar have an inlaid centerline or inverted triangle? If so, is it platinum, gold or white? I would use the same for the bead or you won't get the proper contrast in bad light. Most of the English rifles came with an inlaid platinum center wire and a German silver bead. Given a choice, I like German silver best, with an .080" bead on a big rifle and an .065" on a medium. Ivory or porcelain works well on a folding moon bead.
