Christofle, triangle mark

[yan78]

Hello, please try to help me to identify silver mark from christofle´s teapot.. it´s a triangular mark with R 07 inside.
I found also similar marks with R 09 or R 20.




Thank you,
Yan

Hello, believe Christofle used this mark on refurbished pieces. "R" is for reargenture, the number ist the year, "20" for 1920. Remember dimly that a dealer told me this, no idea whether this is true. Best wishes, Bahner
