No doubt in my mind. A really good antique St Louis Camomile weight on a Tomato Red Swirl.
I produced many photos of a superb collection of antique French weights for a booklet of the Paperweight Collectors Circle 25th Anniversary Exhibition in 2006. One of the weights was just like yours, except that the bud was to the left of the flower. The colour and structure of the Camomile flower head, the leaves and stem, and the Swirl ground were all much the same as yours. There was another St Louis Camomile weight, on a white and pink swirl, which had the bud to the right.
Wonderful weights with a retail price to match!
