I'm wondering if any of you can help me date this drum. As you can see, the tag says Cleveland and has a 4 digit serial, but I know that's not necessarily an accurate measure. The Clockface is elongated, and I thought those didn't start appearing until after 1967, so I'm thinking maybe it was actually assembled in Dayton? I've included some other pictures as well, as I'm sure there are other clues I'm overlooking. Thanks!
