Teapot Christofle

Hello, I have this Christofle teapot and I personally think it is a true work of art in metalwork. I would like help identifying which year this piece would be from, please?

The serial number is 1230994, which suggests to me that it dates back to the mid-1890s, but there are those 4 3s, which leave me in doubt as to what they refer to. Another question, could anyone tell me if Christofle ever restarted the counting of its serial numbers? Thanks in advance.

The 43 refers to the amount of silver used in the electroplating process.
