I have searched and not come up with anything. I have also searched the US Patent records website. So, my question is, what year was the patent for the American Standard basses granted? I am trying to date my bass, and the serial number info just points between 1925 and 1939. But, at the bottom of the label, it says "PATENT APPLIED FOR." I am hoping this can narrow it closer than a fourteen year range. FWIW, it is "NO. 410"
