Silver cauldron 4-footed salt cellar- Identify please

Hello, I need some help please , I have had this cellar for years and Have looked it over extensively and I can not find any type of Hallmark and I found that quite odd. There are two very small Triangle type marks and a spot on bottom That looks more like maybe a weak spot very tiny. I really hope someone knows more a Maker or maybe could Date it to a period. It seems quite well made and It seems there was a gold color on the inside at one time but is wore down. also on the leaves on side. It measures only 3 1/2" x 2 " in Height , Thanks Ahead for any comments to my post .
