Antique SILVERPLATE French authentic Art Nouveau SunFlower Posy Vase w Glass Frog Marked?

Antique SILVERPLATE French Art Nouveau Flower Vase w Glass Block Frog Marked? Lovely and Rare!

In good usable antique condition, has a couple of slight dents (nothing glaring) and tarnish, needs a proper polishing (if that's how you like it), not sure if the glass is original but was found with it, see photos. Stand measures 5" tall to top of frog and 4.5" across the widest point, the lot weighs .571 kgs unboxed. Not sure... could just be a ding but more likely a touch mark... looks similar to marks used in France, very tiny, any info would be welcome (see last 3 photos). Would make a great addition to your collection to use and display! Shipping costs are for U.S. & Canada, any other country please contact me with your address for shipping rates. I do combine shipping for multiple items when possible. Thank you! authentic
