Help please ID teapot hallmark

Hello, I acquired this teapot that has unusual hallmarks. In the center is a star with smaller stars surrounding it. To its left are the letters RIM. Would you have any info? Thank you!

I can’t identify this for certain but I think it may be French electroplate with the number 15 signifying the number of grams of silver used in the electroplating process.


Thanks, Phil. I thought perhaps the stars meant it’s Spanish in origin. But I wondered about the 15, as well. Best regards, Herbert
