We've recently received some new Lange company Orpheum serial numbers for our list. So, I've made some changes to the Wm. L. Lange side of our Orpheum banjo hypothetical serial number date chart. From a review of the "literature" it appears that production of Orpheum banjos stopped in 1928. I don't think Lange was manufacturing Orpheum banjos in 1929 but I left a line open on the chart in case we get some additional Lange made Orpheum serial numbers demonstrating that Orpheum production continued into 1929.
