I am trying to date my Edison BC 34 baby console phonograph. From what I have been able to determine online, I know that the machines started to be produced in May of 1922. Based on the size of the reproducing horn I have been able to deduce write that my machine was made after June of 1922 as it has a size #150 horn.
My machine has a serial number of: 46408 . It has the 10/12 selection buttons, and a 3 weighted governor.
I am trying to pinpoint a year, perhaps even a month of manufacture if possible.
Thank you in advance for any and all help. I look forward to your responses,
