Is My understanding the old unmarked 61 movement has a steel crutch and the re-issued where brass ? and when what year was they unmarked with just screws holding front plate on.I know some were pinned
From the research I did on the one I have My unmarked 61 is from the mid to late 1880's. The case has the three piece bow, and old black label. Nickel colored beat scale plate, and natural wood colored pendulum. Oh and steel crutch. It has been staying within 2 sec every week & a half to two weeks Steve
