Christofle Mixer Wheel, Is this Silver ??

Hi everyone, I have a couple questions. What the heck is this thing? Christofle mixer wheel ? It says Christofle and Le Bar Plaza Athenee Paris. I have never seen anything like this. It looks and feels like Silver. It lists different cocktails around the wheel then you turn wheel and has numbers in like pie slices. I really have no clue. Any help would be greatly appreciated. Thanks in advance, and I hope everyone is well.

 

It's silver plated.

Looks like recipe thingy that you have to line up just right to see how much of which ingredient(s) you need to make the drink on the outside edge.

 

A recipe thingy, hmmm, that's what I thought. Thanks so much!!

 

lovely. and rather rare. probably just after 1945. I can't imagine that the French mixed such ingredients like cranberry juice and raspberry sauce before the Americans came.

 

Thank you Fid!! I did see another one sold on some website, I forget which one but ya, it was described as made around 1950. Thanks again!!
