I've seen single-letter markings occasionally on B and Q Graphophones. I'm not sure of their purpose or meaning.Phono-Phan wrote:I still wonder what the U stamping indicates. Possibly an inspector marking? or an employee ID marking?
Keep in mind that by purchasing the $1 box, any Q could be made into a QB. Unless we can trace the provenance of two QBs back to purchase, serial numbering won't be helpful. In addition, dealers could make up QBs from their existing stock.Phono-Phan wrote:Is your serial number earlier or later George? I would think that your base is more stable and a later improvement from the flimsier framed base.
I don't see a stability advantage to the recessed design, but the possibility of pinched fingers between the key and base would have been a definite "improvement!"
