The Talking Machine Forum — For All Antique Phonographs & Recordings

When I was cleaning the Grafonola yesterday I noticed this mark stamped on the motor chassis. I thought it was kind of interesting, and something I had overlooked before. Does anyone have a clue what its stands for? Does it give any indication about the age of my machine or where it was made? Just curious if anyone was familiar with it. Thanks.

I think it recent mod meaning "This machine was serviced by Frenchmarky"
